I have a 1990 chrysler, new yorker with 185,000. 3.3 ltr. V-6.I recently replaced the valve train on the 1-3-5 cyln's and had no problem's reinstaling everything, but when I reconected the battery and started the car, the motor started racing to beat the band.I've replaced the (ISC) motor and made sure the air flow is not restricted to the throttle body and oh yes I also replaced the throttle body but still have a racing engine can you help please!
