My Fiero has a hard time idleing when the car is moving, idles fine when it's sitting. I have WinALDL and can monitor the sensors, but not sure if the numbers are wrong or not.
Also, I have an 85 V6 ECM, but swapped it out with an 86 V6 ECM (7170) to see if that was the problem. Where I choose my ECM, do I choose 86 2.8 MPFI or the 7170? And do I need to connect the green wire so it runs in diagnostic mode or leave it disconnected?
Right now with the green wire connected and the car not running, TPS is at 43.
What sensors would have to do with my idle (TPS, MAP, IAC?) and what should they read?
Tell me what to do, and I'll log it and send it to you if you can help.
I've replaced/swapped everything and nothing fixes it.
 My Fiero is turbocharged and usually uses the 6869 ECM with a 2 bar MAP. I swapped it for the 7170 with a normal MAP to see what happened.
