Hey all i still haven't found out what CO means on my fuel computer, but there's another problem.


Wheni drive a few miles and stop, i feel a shock when i put the car into park and the RPM starts to rise to 2000RPM and when i give a boost with the gaspedal it lowers for a few seconds and the rises again to 2000(the same with neutral) any ideas what can be the problem???

 

what kind of shock? like an electrical shock?
