Update:
I'm going thru the Idle surging checklist. I set up the throttle plate stop screw at 0,010" plus 1.5 turns, TPS at 0.991 Volts. I haven't started the car yet to verify the base idle rpm with the IAC valve disconnected.
Prior to this, I put some smoke into the manifold to check for leaks. Smoke was coming out of the EGR valve, not exactly where but it was coming out all over the valve. So guess what??? I removed the darn thing!!!! I had a 5/8" plate so I did the whole thing...
At this point I don't have a TwEEcer to remove the EGR function from the ECM, but I will follow
Mustang5L5 advice from another thread about NOT to use the EGR delete plug so the ECM disables the EGR function with an error code avoiding possible detonation by the ECM adjustments when trying to fool it with the plug. I know I will be seeing the CELL flashing which I really hate but for now it will be like that. I'm I doing this the right way???
On the EGR removal subject I have an interesting question based on these next scenarios:
Scenario No.1).- If I remove the EGR and before I start the engine I use the plug to fool the ECM, and then I start the engine. There should be no CELL light so the assumption is that the ECM thinks the EGR is hooked up and ready to run so the ECM starts making adjustments to timing and fuel.
Scenario No.2).- If I remove the EGR and start the engine without using the plug. The CELL will start blinking and as I understand the ECM once it senses the absence of the EGR it will throws an error code which according to Mustang5FL5 the ECM disables the EGR function.
So here is the question: If I follow scenario No.2 and if after the ECM has an error code and has disabled the EGR function I use the plug to shut down the CELL blinking light the EGR will remain disabled?
Please confirm or reject the theory on my question.
Thank you all a bunch!!!!!
