thought i had a lift pump going bad on the way home. checked the fuel pressure and have 12 psi. my truck loses power. then just like flipping a switch, it is back again. although it had 12 psi and was still doing it. im going to check for air leaks next. my engine does have a different sound to it when cruising on the highway. it doesnt sound smooth. it started when it got cold so i figured it was from the cold. but maybe not. anyone have any thoughts?
dm, i meant to look at your pusher pump while i was down there. never remember things till it is too late.
