Could be your throttle position sensor failing. It sends a reference signal to computer as to where the throttle is. Should be showing .5 volts at idle and smoothly climb to 4.5-5 volts at full throttle. If the signal is anything other than this or it jumps around as throttle is moved your car will not run properly.


http://autorepair.about.com/library/firing_orders/bl-fo-7066.htm -- check this out if there is a chance that the plug wires were not installed in the correct order.


Was it acting this way before you did the work on it?
