Quick back story: Bought the car 5+ years ago with a stock SR swap. Ran damn near perfect. Upgraded to Haltech, 550's and a GT2871R. Now I've put the stock ECU, injectors, MAF and turbo so that I can sell the car.
Everything went pretty well, it's just that the car doesn't run exactly like it used to years ago when I got it stock. It's idling rich (10-12 AFR) and misfiring a bit when the engine speed is increased.
Is there some kind of re-learning process the ECU needs to go through? I had to reset the ignition timing. But how about the TPS? Or idle? Something else?
I'm thinking the car might need a boost leak test, because the Haltech used MAP so minor leaks did not make a difference. Being on MAF again, it does.
