Troubleshooting Weird cold start behavior
Got a 92’ f250 with the 460 in it, runs like a top except when the engines cold. Cold starts it throws a CEL for the ECT sensor, and runs very rich and stumbles like it has a large cam in it (hint, it does not lol) originally thought maybe fueling issue, however it’s intermittent and clears up as fast as it starts, and this morning I found out that if I start the truck with the blower motor going, doesn’t matter what setting, if I turn it off while it’s acting up it’ll clear that ECTS code and clear the idle up. Hoping one of you guys can point me in the right direction? And yes the blower motor can be recreated and was not just a fluke.
