I just put a fuel pump, fuel filter and 3 rebuilt fuel injectors into a 1997 Yukon. Prior to all these being replaced, the truck had alot of hesitation when first taking off from a cold start. I thought these new parts would fix the problem but it is stilling doing it. Any suggestions on what to check next? The problem has been looked at in the past but no one seems to know what is causing the lagging.
have the same problem?
