First off this isnt for my 3rd gen but for my winter car (91 cutlass cierra 3300). So far its been stalling at idle intermittently and there is an intermittent hesitation when accelerating too. I put new plugs, wires, fuel filter, air filter on it and cleaned out the IAC sensor and put a new MAF sensor on it too. Its not the injectors either, i swapped them and ran cleaner through it. I replaced any cracked vacuum hoses. The only other thing I can think of is a dirty EGR valve, im gonna try and clean that out and see, im pretty sure thats it but i was also pretty sure it was the maf, vacuum lines, iac sensor, etc also. so i dont know what do yous think?
