LTFT% B1 Problema'...
LTFT% B1 Problema'... Vehicle only does this on initial startup and only when in gear driving at low RPM. It snaps, pops, and shudders for a few hundred RPM then mellows out as you get moving... Once engine is warm you can drive it and problem is gone. So basically when engine is warm there is no issue. Recent modifications - Headers/True Dual Exhaust/Spark Plugs. The O2 sensors were extended using the Pacesetter included extension kit. Anyone know what the hell is causing the LTFT % B1 to go crazy all by itself? Looks to be the culprit IMO.
