Ever since swapping in fms 30lb injectors with the proper tube for the c&l, then car will not idle normally. Its either at 1200-1500 or it'll idle around 900 and/or surge and stall. It can NOT be driven this way. I have set the idle many times and it does nothing. I had the set screw backed off all the way. I also have the ford idle adj plate. I set and checked tps, cleaned the IAC (its new btw) cleaned tb, I pulled the throttle cable off w/ the car running to verify its not the cable and no change. When I pull the connector off the IAC the idle doesn't change. I have pulled the harness off the tps, maf and egr sensor (1 at a time w/ the car running) and I get a check engine light everytime leading me to believe the sensor are working fine. This is a total nightmare. I think its just the computer being gay and not reacting nicely to the injector swap. I am planning on a custom dyno tuned chip to fix that problem and tune the car. Anything else I can check before doing a chip??
