stalling in low RPMS
1,105

Asked by texascowboy1809 Sep 14, 2009 at 11:56 AM about the 1990 Ford F-150 XLT Lariat Extended Cab SB

Question type: Maintenance & Repair

Truck has a 302 sb 5.0L engine. Whenever i have it in low rpms, the engine just dies. no warning, just dies. it cranks back up just fine, but within a few seconds it just dies again. Recently it had the Intake Manifold gasket replaced, and im thinking this could have something to do with the issue. it never did that before the repair.  Got any ideas?

check all ur vachum lines to make sure u didn;t mix them with an egr line, check the maf sensor to make sure that it's sending the proper fuel signal to teh computer, teh problem could b the injectors not giving enough fuel at a low airflow

well, i dont understand why exactly, but the shop i took it to said that it was a pinched fuel line. something just doesnt sound right to me about it.

yeah, mine does that too when I first start it up, it revs itself a bit when it gets close to killing over, and after I rev it once, it's fine. but mine only does that right after you start it, and after I rev once, it purrs pretty good
