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.

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