The car ran fine and the light stayed off for about 2-3 days and now it is back on with the same trouble code. It usually comes on when the car is started and is not 'actively' moving. As long as I start driving right after it is started its fine, but if the car is started and say I have to wait to get out of the parking lot, the engine starts spuddering and shaking and the check engine light comes on.
This problem has been dramatically reduced since the new plugs and O2 sensor, but it still happens every once and a while.
Another issue (I dont know if they have to do with each other or not) is when I am driving the car, and am driving anywhere over approx. 2500 rpm, when I shift into neutral, or just put the clutch in, the rpms fall VERY quickly to about 500 or so rpm (this causes the voltage meter to drop) and then it jumps back up to where it should be around 1100 rpm.
What could be causing these problems? Thanks!
have the same problem?
