Bought this car for my daughter 2 weeks ago.
I had 3 problems but I think I have one of them fixed.
Now my worst problem is rough idling when the motor gets warmed up while sitting at a stop light or stop sign. Its bad and nearly stalls, but traveling down the road it runs great.
I cleaned the MAF sensor, changed plugs, changed one coil, one coil boot, the air filter and I removed the throttle body and cleaned it.
Nothing seems to help.
