My wife's Camry went in to the shop 2 months ago for a rough idle. We bought the car used in February with 72K miles. We've put on 10K and decided to have a mechanic look it over and tell us what it needed. The shop noted the engine left and right engine mounts were broken and suggested we change them (for $600). I decided I could do this job and save a few bucks.
So, yesterday I replaced the three mounts underneath the engine with toyota factory parts from the dealer. Also replaced the dogbone up top. Four mounts replaced. The problem now is that the vibration has changed. The car used to have a pretty steady vibration, most notable at idle in gear. It would also lurch when accelerating from a stop. Now the lurch is gone and the car feels smoother while driving and the lurching from a stop is gone.
But, I only have vibration when at a stop and the car is in drive. Putting it in reverse, neutral or park and no vibration. I can also kind of feel the same frequency vibration when I turn the car to the left. It makes no sense to me. Tonight I cleaned the throttle body as detailed here: DIY 2AZFE Throttle Cleaning Gen 5, Gen 5.5, Gen 6 - no change on the idle.
I pulled the wheels off and jacked it up and got under it and looked everywhere while having my wife put it in drive and hold the brake. Engine is vibrating a good bit, but the mounts look fine.
I can't figure out if it has anything to do with the engine mounts now... Did I do something wrong or is something making the engine run rough at low speed? Did I get a defective mount? How can I troubleshoot this? I'm scared to take it to the mechanic and go on an expensive goose chase after already spending $400 on mounts alone. Any suggestions are welcome!
