ALSO id like to ad that certain vibrations can happen at certain RPM's.. try getting it to duplicate at a specific RPM also. i have a rattle in my crx at 4400rpm's and it drives me insane cuz thats my cruzin speed in 5th gear.. around 62-65 mph... still havent found that damn rattle either.. too lazy to get someone to ride with me

The noise only happens at idle goes away when the engine is revved even a bit and then comes back when it settles to a stop. But that happening only sometimes is annoying because there's no way to duplicate it other than driving the car a bit with the tech there and then stopping and listening for the sound. I've done this 3 times already and for some reason I can't get it to do it when theyre in the car. ha go figure!
