I just bought this car and the "check engine soon" light stays on. Also, when I put the car in reverse I hear a clunk noise then when I put it back in drive it does it again. It sounds as tho something is breaking. Nothing seems to be broke to the eye but, then again I am no expert. What do you suggest?
Thanks in advance, Lisa email: "firstname.lastname@example.org"
Hi, the clunking sounds like a constant velocity joint (C V joint). It is usually better to replace the whole shaft (half shaft). Yes there are 2.
The check engine light can be checked at any Autozone or similar store. They will put an ODB2 scanner on it for free. Thier diagnostic machine will give them a code similar to code 34 or something like that. This is where they mess up. They don't know what that means. You may need to get the code and do a little searching yourself to get an acurate meaning. DO NOT BELIEVE THE AUTOZONE EMPLOYEE INTERPRETATION ON THE DIAGNOSTIC. Do the search yourself.
Good luck and let me know how it turns out. James

If it is a four wheel drive check your tail shaft or drive line by securing the vehicles front wheels jack up the rear tires and in park try to rotate the drive line if you can hear the transmission sound like it is going into gear the transfer case could be damaged! If not a four wheel drive pull the transmission dipstick and look to see if the fluid is dark red or metallic grayish color if so then you're clutch disks inside the tyranny have been worn out and it needs to be rebuilt!
Sounds like a drive shaft but you would hear a clonking noise so it could be the clutch gone ,if i was their with it infront of me i could soon tell you the problem but from afar ? ask a local mechanic to have a look for you as this is one of them questions its impossible to give a correct answer
What kind of noise? A clunk, chatter, whir, grinding, or what? If it's a clunk, you may have a worn U-joint. Test by holding brake on and change between drive and reverse and back. If you hear a "clunk" when the tranny engages, it's probably a worn U-joint. Not a hard repair to do in the driveway. Always change BOTH front and rear U-joints - if one's worn, so's the other.
could be a blocked cat converter or a trans issue,,,usually a severe problem when the service wrench light comes on versus the service engine soon light, the wrench light means more important problem,,i would take it to delaer
This sounds like one or more of your motor/powerplant mounts is broken. Here is an easy test:
Have someone sit in the driver's sear with engine running and trans. in Park.
You stand in front with the hood open. Have them shift from Park to Reverse, and then Drive and back to Reverse and Park, taking time to stay in each gear and give some throttle while holding the brake pedal tight. This will rock or move the engine a certain amount as they shift through the gears and apply power lightly. It will move alot more violently with broken mounts.
If you have a clunking noise on Reverse shifts, you should be able reproduce this with the hood up and pinpoint the noise and/or sight the faulty motor mount with a friend's help. Good luck, I hope this puts you on the right track to fixing this annoying noise.
It would be helpful to determine if the clunk was transmission related or happens when braking or parking.- And if it's engine bay or rear noise.
It could be as simple as an unsecured jack rolling about, or other heavy equipment, Play in the seat rails, Seat belt tensioner mechanism, Battery mounting, Radiator mounting, Loose Brake caliper, tight damper, play in damper support, road spring seating, engine/ transmission mounting, noise in wishbone assembly joints.
Hope you resolve this issue soon.
If it turns out to be any of the above, Please rate as Fixya, or "helpful" if it genuinely was.
