2000 Chevy 2500 6.0 LQ4 The truck starts fine, but runs like crap for the first 15-30 seconds or so before it cleans up. Happens even when i've been driving it and it's warm. It is also going into limp mode randomly when I'm just running around town. No codes and completely stock truck. I've changed fuel filter, air filter, plugs, wires, coils, intake manifold gaskets, O2 sensors, new MAP sensor, cleaned MAF sensor. I'm at a loss here....... Anyone know what else it could be? Thanks in advance!
