well heres the story
i have an 05 dodge ram with a 100k on it and motor went while i was driving it one day. ordered replacement engine form dodge and installed it with no problems it bolted right in. now im having a couple of issues truck will not idle . truck is runnign very rich pulled spark plugs and checked them were soaked with fuel. i have access to factory equaivalent scan tools like snap on motis and otc genesis and monitored all data and comparing it to known good ram data have found it within spec. the only thing that is coming up off is long term fuel trims -35. i have checked battery and all connections and came up good. tested and replaced o2 sensors and still no luck. checked throttle body and cleaned with no success. even had a friend with a starscan from dodge come down and he said all data looks good. checked fuel pressure with mechanical guage and looks good as well.i am stumped with this problem. there are many other things i have checked and all came up good. the truck will still not idle. the only way i got to idle was to create a vacuum leak (pulled line of booster) and she idles but is surging. have reset and relearned cam and crank sensors. any help would ne appreciated
