Hey everyone!

Got an 87' f150 302 that is stalling while idling in driveway or at the lights. Just wondered if anyone had any ideas about how to fix. I'm thinking that the battery is getting weak and the truck is solely running off the alternator to run injectors, fuel pump, etc. Always stalls while stopped. Thanks

if you think the battery is weak have it load tested to see whats going on.if the battery is good you have to work from there.maybe an alternator due some research w/ the battery and we can go from there.

 

Check for vacuum leaks and check the IAC valve. Other than that, it might be a clogged fuel filter, but I doubt it.

 

Error code scans, have battery Load tested & check Alternator output.
