Trying trying to change spark plugs and cylinder one boot looks different than the rest. It’s a 1998 Honda Honda Accord.

My husband attempted to do an oil change on my 2016 mazda cx9, the next morning I tried to back out of our driveway and i hit reverse and it went in reverse and then i put it in drive and it went into reverse, so then i tried to put it in reverse and it went into drive. I immediately put it in park and turned it off. I waited about 30 minutes and it went into drive correctly and i was able to park the vehicle in a perfect position but then when i put it in reverse to back it up a bit, it just stayed there, rpms did go up, but no movement.
he later called me to tell me he accidentally drained the transmission fluid and added the new oil into the old oiI. after learning this, i didn’t drive the car for two days, and he eventually added the amount of transmission fluid he drained and drained the motor oil and added the new oil. He drove it and checked the levels and everything was fine. We drove it the next day all day everything was good. I drove it to work and back and everything seems fine, i’m just hyper vigilant now on every little slight movement in the vehicle since my last vehicle (gmc acadia) went to shit, transmission definitely went out on me while driving. today he drove it to lawrenceville (we live in powder springs) and back home and everything was smooth. I’m just worried and nervous when i drive the car. My question is; will the car be fine?

Had the death wobble for the first time on my way home and had to come to a complete stop for it to stop. Drove about 3 hours today and had the same thing happen. Noticed my truck was over heating, pulled over and put coolant in it since the tank was empty but the reservoir was full. Drove about another 2 hours and it over heated again, reservoir was empty. Put coolant in it, made it home but there is a small portion of the coolant missing.

Any ideas as to what’s going on? My fan has always ran when driving the truck so I’m wondering what the issue may really be.

I have a 2015 Chevy Malibu and my brother dipped my car key into a candle and I didn’t really notice till I had already put my key in the car. I took it out after and cleaned the rest of the wax out and went in my ignition with a Q-tip and a bobby pin…(sorry) now it’s kind of just a greasy residue and I’m kind of stranded in Indiana visiting my mom and I have a 2 Hour Dr. home tomorrow. I’m 17 years old so it would be a lot of trouble for me to call a mechanic to look at literally nothing. Do you think I’m safe to drive home?
Or anywhere actually

Just had my 2009 Mazda 2 1.3l serviced and the mechanic used 0w-20 when the specifications say to use 5w-30. I questioned him on it before he put it in and he insisted it’s fine and it doesn’t matter. I’m not sure whether to believe him.

Is it likely to cause any damage to my engine? Is it safe to use until next oil change or do I need to get it changed immediately?

Hi friends. A plastic water bottle cover clung onto my girlfriend's exhaust pipe while driving and the plastic seems to have melted on from the heat (idek how it managed to stay attached at freeway speeds). Does anyone know a way to get something like this off without damaging the exhaust pipe itself? Any advice would be helpful. Thanks!

Trying to get this old beater truck I got for free passed the safety on the cheap so I can transfer the title. Trying to do it on a budget. I know i could new shoes on here easy enough, and have the skills to do it, but it seems like there is a fair amount of pad left, but i'm worried that they'll fail me on those chipped corners. thoughts?

Hey everyone, I originally took my 2004 Toyota Camry V6 to the shop to get a vehicle speed sensor replacement to solve this issue but it wasn’t the case.

I ended up replacing the transmission as well and I’m still having this issue where my speedometer doesn’t register and the RPM stays stagnant(sometimes drops and causes my RPM to shoot up)

My mechanic tried to trouble shoot and figure out the problem but could do so..

I was wondering if anyone here would know?

2011 Hyundai Sonata 2.4L 4 cylinder. Noticed light smoke and burning smell coming from under hood. Opening hood saw smoke emanating from rear of engine, toward the line that plugs into exhuast at bottom of the rear of engine. What is that line - it looks damp/black at the connection. See pictures / video. Is this a manifold gasket leak? Coolant? Something Else? How critical is this to fix in a timely manner? Can I try to tighten the valve cover bolts?

Hi everyone,
I received a brand-new SACHS clutch kit (part number 3000 951 790) today.
When I unpacked it, I noticed a green, viscous substance on the back of the dual-mass flywheel. It looks like it might be coming from inside the flywheel.
I've attached some pictures showing the substance and the areas where it appears to be leaking.
Has anyone seen this on a brand-new SACHS dual-mass flywheel?
I'm wondering:
• Could this simply be normal grease, or does it look like a leak?

• Could it be a manufacturing defect or damage caused during shipping?

**• Would you install this clutch kit as it is, or return it and request a replacement?**

I don't want to install it only to discover later that the flywheel is faulty.
Any advice or experience with SACHS dual-mass flywheels would be greatly appreciated.
Thanks in advance!

I’ve been going to this shop for awhile. I have an older car that was having some issues and well this is what they quoted me and I’m curious if something like this is reasonable. I declined the repairs but only because I’m planning on getting a new car anyways but sheesh

Edit: THANK YOU everyone. Went back and politely told them that that was unacceptable to charge me for a full hour of labor and after 30 minutes of politely advocating for myself, they refunded me $165. Thanks Reddit. ❤️

Also: to answer everyone. It was like $225 for labor, $100 for the belt and $50 in “fees” originally 💀

And yes… just the belt….

Good afternoon folks! As the title says I’ve got an 07 Tahoe that won’t start after removing my father’s lights and siren from the vehicle. I was able to run it fine the next day with no issue, but after letting it sit overnight, the car will not come to life. I’ve included a video of be attempting to start the car.

My initial suspect was an automatic starter put into the car, but after disconnecting it, the issue still persists.

My intuition is telling me it’s a bad ground somewhere, but I would like to verify with others before diving any deeper.

any advice or further questions are more than welcome! Thank you for your time!

I recently purchased a used 1998 Dodge and have been having issues with the radio producing sound. The radio works (display and all buttons as far as I know) but didn't produce any sound on am or fm.

I had the battery replaced today as it died and then the radio worked, initial lack of sound was probably caused by the old battery. The radio worked fine until I got to my first stop of errands. After getting back in the car, the radio was super quiet even with volume maxed. I got back in the car to go home and the radio wasn't producing any sound, nothing on am or fm, not even static. Do I have to worry about another issue with the battery or is there something up with the system itself?

What would I need to be looking for/ what could have broke that could be causing the issues with the lack of audio?

I’m considering using the AGA Tools Clean Oil Vacuum Regulator with a Milwaukee 2.5-gallon wet/dry vacuum and the AGA Tools Clean Oil Funnel Kit for oil changes.
My main concern is whether using this setup over the long term could potentially cause engine damage, such as damaging seals, gaskets, or other internal components due to vacuum pressure.

Has anyone been using this setup regularly for an extended period? Have you experienced any issues, or do you believe it’s safe for long-term use when used correctly?
I’d appreciate any feedback or firsthand experience. Thanks!

I’ve got a 2004 Toyota Tacoma 2.7l 4 speed Auto trans and I’m pretty sure it’s slipping when I’m going from stop to accelerate. I think it’s slipping cause it revs high when the wheels are barely moving then afterward I accelerate faster. Got a video attached.

Appreciate if yall could tell me what ya think 👍

I’m doing a timing job on my 2003 mustang gt and I found this grounded circle on my timing cover around the front main seal. The crank position sensor wheel isn’t damaged or grounded down. My research points to this being normal. I’ve seen pictures of other timing covers looking similar but I want a second opinion.

Can somebody please tell me what’s wrong 😭 my car been down for two weeks i honestly was just hoping it was the battery but I replaced the battery, and the lights came back on but when I tried to start it I heard one click. The dashboard lights stay on but my AC and power windows won’t work and the engine won’t turn over. I have had issues with the positive battery cable before. Could it be the cable, a bad ground, or the starter? Has anyone experienced this? I’m trying to figure it out without wasting more money on parts. Any advice is appreciated!

Car stopped running while driving, engine turned off had to pull over. Any idea what it may be ? Bad battery or starter ?

EDIT:

-Car doesn’t crank at all
-Electronics still work
-Fuel is working
-Dash lit up while driving, engine shut off and I had to coast the car to the side of the road
-When I try to start it up, half the lights go out including the in car rgb lights

Note: no lights were on prior, was driving car and it was starting to switch gear, the whole dash lit up engine shut off and i coasted to the side of the road.

I originally thought it was the starter, so I replaced it. This did nothing. I then asked chat gbt for advice and it recommended I put it in neutral and try to start it. This worked… 1 time. I had to turn it off immediately because I still had the manifold partially disconnected and it started shaking. I went ahead and hooked everything back up and tried to replicate the crank but I cannot get it to turn over again.
The battery is on and going strong. I tried jumping it just to be safe which did not improve my situation.
I saw somewhere about changing the starter relay fuse but my car does not have a traditional fuse for this and is integrated into the fuse box apparently.
Any help or past experience anyone can share would be very helpful.

Hit a racoon somehow he just hit my fog light and walked off how can i fix this? What if all clips are broken would love to be able to fix this myself for as a little as possible 😂 please and thank you
