miata won't run at idle
 

Hey again. Ok.. I have a '95 miata with a '97 donor motor that I transplanted. Used all the old wiring and old ecu and from everything i read, as long as you use the old wiring and fuel injectors that things should work just fine. BUT... The bitch starts and then immediately shuts off after a second. It has fuel and spark. Checked the ecu (morse code style) and it says IGF. SOOO ignition signal is not getting to ecu? Checked and rechecked wiring... any suggestions?

:crx:

WOO got it runnin!!! The coilpacks are different from 97 to 95.. so switched them back to the old ones and it runs oh so good. Not even a check engine light.. :fawk:
