So my parents have a sc400 just sittin in the garage they drove it a few times and i drove it for sum reason when hot the car idles ruffly?? is that common,you can barely stop the vibration when your at a stop light with your foot to the floor while on the brake.

wat could it be?? also the car is barely drivin from time to time. We changed the timing belt thinkin it was that but it wasnt.

all inputs are welcome!!

 

i have this problem with my sc300...and only sometimes and after the car has been driven for a while. I have a 1j swap too btw..any imput would be most appreciated- other than get a 2j JEROME!!!!!!

 

i dunno wat it could be that causes the car to vibrate at idle??
