Hey guys!!! Ive noticed recently that my JDM Corolla sedan idles roughly.Wether or not the A/C is on.The vibration can be felt by everyone in the cabin of the car and I feel it through the steering wheel and brake pedal.Ive have changed 2 engine mounts, had the plug wires, plugs and distributor checked and everything is fine according to my mechanic.Last week I tried some injector cleaner but it hasnt seemed to work.I have also checked the PCV valve and it isnt blocked.What else could it be??? I am almost at my wits end as the rough idling is getting on my nerves!!!! Ive also had the timing checked and it is okay as well. Any help here would be greatly appreciated.My car if you guys remember is a JDM Corolla sedan equipped with the 5AFE engine...here are a couple of pics....

Is your idle RPM higher or lower than before the vibration started?

what does the engine idle at? if its below 750rpm could be your problem. should idle at 750rpm and 800rpm with headlights on.
