I believe the stock ECU was compensating for my idle speed motor (which may or may not be throwing off my dwell reader). With Dave's ECU being more strict on function, it has a "rubber band" effect when taking your foot off the gas as it tries to hold the idle.
I performed a full closed idle test (mode switch 7), but the car would die, and give me 3 flashes of a green light on the ECU board.
Adding in all the noise now coming from the back, and that my last vacuum smoke test found smoke coming from the Idle Speed Motor, I'm going to swap it with a new one to see if there's a difference? #vin4693
