So, starting about 3 days ago I had this problem. I drove the kroger after work (car ran fine) I came out got in the car started it and the car started fine and ran fine for about 10 seconds as i was pulling out of the parking lot the car started to idle super bad, i tried to give it a little gas but the car would die in revs when given gas then rev up when i let off the peddle. Also to get the car home i had to limp it the whole way. It would buck really bad in gear at a constant rpm. Its my only car and my only way to and from work so i need to fix it asap.
I have tried all of the following:
TPS (Throttle Position Sensor)
IAC (Idle Air Control Valve/Motor)
Replaced all of the injector O rings and cleaned the injectors
Checked Timing its set at 14 deg. with 93 octane
Replaced the MAP sensor (Since the car is Speed Density)
One thing that did make a huge change is when i unplug the MAP vacuum from the MAP the car will idle and hold revs along with the peddle when i rev it up the car revs with it instead of dieing. Only problem with that is the car idles like crap with the MAP vac disconnected.
