91 duel cam sputtering at idle...help!!..

[DTMpower]

I already did a search on it and no one had exactly what I have....the car runs fine when normal driving but when its idling at a light or just in park it sputters and it seems like its about to stall..so i have to kick it in neutral all the time...it has a injen intake and a 3" cat back(got it for free so i put it on)..it had a injector problem before but my mechanic replaced the 2 that were not firing....please help...i gotta get this car on the road...thanks in advance.

clean out your Idle Air control Valve, there is a thread on here somewhere. Search and ye shall find.
