ECU heat soak

Recommended Posts

So as my car is up and running and can drive it...


im throwing ideas around trying to diagnose the problem.


it runs flawlessly at night when it’s slightly cooler but during the day when it’s warmer it develops a misfire and drops what I think is one whole bank. Will sometimes come and go other times will change with throttle input...

could the issue be the igniters in the ecu are getting too hot?

there is quite a bit of heat from the engine bay…definitely won’t need the heater in winter haha
