Runs Bad Cold

Ok, here is the deal. My truck will always start, even on the coldest mornings. If I don't let it warm up completely though, it will get about 1/4 mile down the road, start knocking while losing rpm, then it will die. The only way to re-start it is to WOT and crank for about 30 seconds, and then it seems like it comes to life one cylinder at a time. If I plug it in at night, it's ok, but will stumble a little bit at that 1/4 mile mark.

I pulled the codes, it had four:

P1249 Waste gate fail steady state test

P1209 Injection control system pressure peak faullt

P1211 ICP not controllable - pressure above desired

P708 Trans range sensor circuit high input

Any ideas? Thanks in advance.

From codes alone, that ICP sensor sounds like it could be reporting higher than actual. Unplug the ICP, then try to start and see what that does.

Have u checked your engine oil level lately? A lot of the ones that have reported those symptoms have been a few qts low on oil. It happened to me and I thought not my truck when someone asked me the same question. Its cheap and easy and prob not it, but something to throw out there.

Finding out where the oil is going (on the ground or out the tailpipe) is the hard and probably expensive part.
