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!

BTW - anyone reading this in the future. Listen to the internet and buy factory motor mounts. OEMs off the internet do not fit right. I made this mistake and it was simply a waste of time for me. Factory mounts are >2X more expensive, but they fit... –  caddymob Dec 7 '12 at 3:22

You're going to have more luck asking a new question. –  Juann Strauss Jun 24 at 7:03

Most likely, one of the engine mounts are 'torqued'. You can try and neutralize the mounts. Loosen the through bolts of all mounts several (4-5) turns. Then start the car, and drive back and forth several feet (using quick taps on the gas and not just idling) over and over, and let it rest at idle a few seconds before turning off the engine. Now tighten all mounts being careful not to rock the motor, and don't pry or push anything to reach the bolts! (This is where swivels come in handy)

This is pretty much the conclusion I had come to, but this is really helpful, thanks for the detailed instructions. Will be trying this out tonight for sure! –  caddymob Dec 4 '12 at 23:01

No problem! Glad i could help. –  Drake Clarris Dec 5 '12 at 18:59
    
My 2007 Camry is doing the EXACT same thing!! In spirit of frugalness, any suggestions on which mount to replace first? –  user3056 Apr 22 '13 at 14:18
    
You can usually see one that's torn. Sometimes, it can help to have some one power brake the motor (with the drive wheels of the ground!) back and forth from drive to reverse to see it. –  Drake Clarris Apr 23 '13 at 15:42

I fixed the vibration problem I had for 1 year on my 2007 toyota camry after I cleaned the throttle body and air control valve (iac) the car is driving perfect. I can not believe it was so easy to fix...
