Is it possible to delete the egr and iac?
That seems to be the only things I see causing my problem.
There has to be something,either electric or vacuum causing my problem. I've checked the voltage and ohms.The egr valve has been cleaned and I replaced the IAC yesterday,but no change.Still have to unplug the iac for it to idle back down.
Someone please tell me what I can do? Confused

absolutely...  at your OWN risk..

just block them off..

just leave them Unhooked..

find some company who tunes the ECM you are running..

by the way.  check the ORDER of the drivers side spark plug wires in the clips over the valve cover..   if the last two spark plug wires on the drivers side are run next to each other.. it will induce a spark in the last wire causing it to light the partially compressed air and fuel in the #7 cylinder a quarter turn early.. burning off the fuel and making that cylinder run lean and ping/knock like you describe..   takes just a few minutes to reroute the cables as shown below

did you manage to find a decent book on EEC4 ???

oh.. by the way...  did you ever print out the 4 pages of the EEC wiring diagram for that engine???

tape them together and very each circuit is being properly switched???  like the clutch interlock switch and the coolant temp switch??

run KOEO and KOER self tests with a EEC4 code reader...
