05 Rough cold start and idle
well I have had my 05 for a couple months nowm and it has ran Great until this week. Lows in the 50's and highs in the 80's until last night it got down to the 30's. the past 2 days the truck had a rough cold start idle but after i took off and turned at teh first stop sign it would puff a little blue smoke then it seemed like it idled fine.
This morning however.. started, idled rough as it has 2 days prior, but it would barely move, and it died on me at the stop sign. took a couple tries to get it started and once i did and took off it smoked like a freight train for maybe 2 sec. (i was giving it just enough gas to get it moving). After driving it for 10min and letting it idle for another 10 it runs and drive great.. like it should. keep in mind it was 40* during all of this and still is. i checked teh ficm voltage and bat voltage on start up and batt v is 11v, and ficm is 48.5.
Truck has afe intake, exhaust, EGR delete, new oil cooler studs and gaskets before i got it. 5k miles ago. i since then installed the Blue spring, and PHP FICM tuner. Should i have it plugged in for lows of upper 30's?
