no idle, runs rough

93 Rx7, installed Power FC and car will start when cold, but runs rough, and will not idle. After warm up, will not restart, T/P sensor OK, coils OK, good fluids,good compression, good spark, IAC good, basically all sensors seem to be functioning properly. Any suggestions at all would be helpful.

Started car again and adjusted the throttle as suggested, nut the car still runs rough and won't restart after warming. The car will just spin when starting and the fire seems to come on and off like it will ALMOST start,am I flooding it?

Is the line line to the MAP sensor hooked up right?? one of the vacuum or pressure line should be plugged to the throttle body.. If it gets unplugged, your idle would be really bad.. Also, sometimes its hard to start.. I accidentally didn't hook it up and idle and ran like crap..

By my experience so far, its usually something pretty simple that goes wrong.. you just need to find it..
