Since we are on the fault code, has anyone encouter a P0121 and P1188 at the sametime. I'm use to the P1188 since the car was new but the P0121 is an interesting one. It causes the engine to surge when in idle (750 to 1500+) and the engine to maintain a higher than normal rpm even when you release the gas pedal. As for the vehicle, it is as original as it can be other than the K&N drop in filter. Any idea?
