Not running right when cold, tested FICM and all is good?????
Need some help guys, my truck has been running like crap when it's cold. It cranks fine but just has no power until the motor warms up, I thought for sure it was the ficm but I tested it and even took it apart to see if I could see any weak spots but it was all good (it's a reman that was replaced before I got the truck about 2 years ago). But I can't seem to find a explanation for this problem. Any thing you guys might know to check or try? It's not throwing any codes
