All motor/transmission mounts are new and correctly installed. PCV valve new. New Iridium plugs. Clean throttle body and intake tubing, new air filter and oil change. Transmission fluid replaced with castrol import. Belt Tensioner and serpentine belt is new. Please let me know opinions. Vibration can be felt through fenders, floor, and steering wheel. Have checked exhaust system. No check engine light. Engine vibrate violently, but idle is proper at about 750-800 rpms when warm.
My Corolla vibrates alot in all gears, but less in park and neutral. on 2005 Toyota Corolla
I had the same problem with my 2004 corolla. Toyota dealer in Palmbeach florida cleaned fuel injectors and throttle body ($280)...the problem remained..after googling, i found that MAF sensor needs to be cleaned every 30K miles. Google for MAF cleaning, it will cost you less that 10 bucks and you can do it yourself. Just be sure to use MAF sensor cleaner and nothing else.
Can't say for certain until inspected unfortunately. But, do you know if the engine mounts that were installed are OEM (from the dealer), or aftermarket? I have seen some new aftermarket parts be worse than a broken OEM part. I would definitely take it back to the installer that's been doing your work to have them double check/make sure nothing was accidently left loose or if they installed a faulty mount.
thanks for the response, they are o.e. aftermarket mounts, the mounts have been looked over a great deal and I guess I can buy one mount at a time since dealer price is well over $100 a pop when I got the set of four for $110. But I dont want to go bankrupt over mounts. That is why I drive a corolla, it is suppose to be inexpensive. Shifts are better, but like you have mentioned the new mounts are not oem, sorry I did not include that in my explanation earlier. I have double checked the mounts and none are loose, It maybe a case of a faulty mount. Any other suggestions.
Again, it's hard to say without checking it, but your description sound fairly typical engine mount. I hope you're able to track it down without too much expense.
Okay so I changed all of the aftermarket motor mounts to Toyota OEM motor mounts and there is a huge difference as there is much less vibration, but the issue now is that the engine is still vibrating and can be felt in the cabin. Still no CEL light is on and I can not figure it out. Iridium plugs are the OEM requirement for the toyota corolla so I would rather not put champion plugs. THe corolla has a coil over plug configuration and all seem to be making contact with the spark plugs. please info.
did you ever figure out the problem? I think I have
the same issue. please advise.
the same issue. please advise.
P R Motorsports is on the right path but I may have another suggestion. Sometimes in certain cars putting specil plugs in them cause misfires. Try just putting good old champion plugs in or stock toyota plugs. Also check that all the plug wires are pushed on all the way and snap when pushed on. The snap can't always be heard so you may only feel it.
