Hi everyone I'm new today. I have been watching this forum to get advice as to why my blazer would not start right up after it was warm. It would run great once running but would start hard when warm. Anyway, thanks to every one on here I found the problem to be the fuel regulator which apparantly is common. Truck starts everytime now with no cranking. however, when I'm at a light and idling for a few the RPM's drop up and downto about 350-450 then when i give it gas to go there is a delay. Once im going it runs flawlessly. What could this be? The engine does have an aftermarket intake which i have had for about 5k miles. But this just started after the new regulatar. Any insight is appreciated. Thanks.
