engine issue

fc nut · 07-18-2012, 08:39 PM

the engine runs fine for about 20 min, then it acts up and wants to die. i'm thinking the maf is bad. could it also be the ecu temp sensor? could the under hood temps effect the maf? need help asap! thanks

Ur pic is FC and u call urself FC nut, so I assume you are talking about FC

Check ur Bypass Air Valve

it controls Idle Air, especially when A/C is on.

A very expensive part when new (over 3-4 hundred bucks), you can get a used one fairly cheap from other FC owners.
