Ok, so, I've been having an issue with my new engine runing VEARY rich during cold start/warm up on cold days(-10c and below) After some diagnoses it came to my attention that I neded to replace the ECT sensor and repair the conector, so thats done. Problem improves but still rears its ugly head when its cold. Ran a ECM self test and getting code 11 for all tests. When I drive the truck right after start up it will spit and studder if i press the throttle more then about 1/4 of the way down. Did a fuel pressure test and thats within spec also. Im suspecting it could be the ACT sensor sendinf a slewed signal to the ECM, anyone have any opinions about this problem? Its so bad that the mpg has gone way down.
