Is my new ECU the problem?
Replaced ECU and it cleared the P code, ran fine for twodays. On day three after driving 25minutes shut down came back 5 min. later won’t start. Came back next day started fine. Today, drove 25 min. shut down, 10 min laterwon’t start.
I read all the problems on the forum. Clean the IAC and TBwould be my first step. If this does notwork, how do I isolate whether or not it is the ECU?
Thanks for any help
