As for the cold thermostat, im not betting on that one cause it would run rich when it gets warm, not when its cold. That dude, the EEC IV system came into effect during the conversion to EFI. And yes, you can use a scanner. The diagnostic port is on the passanger side fender. Randywrench, I diddnt even know that you were still here! I did notice the fuel pressure was a bit low and that the fuel filter was stock, so i have a new one. But being busy, this is a tomorrow project. As for the injector driver, it seems that both of them are firing evenly. I'd like to thank everyone whos interested in my case.
Most all use an air temp sensor,but most of em won't effect the run like them old fords will,lots of em are in the air intake snorkel or air filter housing, Thermostat is very important on anything puter controlled as they hafta see 180-190 before they go into closed loop (i.e. control ) anything is possible with the ecm but since the onset of puter cars in 1980 I can probally count on my fingers the puters I've had to replace,and the majority of em where G.M. and any thing with a Mitsubishi puter....
