bobbed83toy 10-13-2002, 03:32 PM just got a bronco from my in laws, its in great shape.. well wife was driving it, came home from work on tues night and the thing would hardly run, so i did plugs, wires, cap,rotor,air and fuel filters, father in law had changed the fuel regulator not to long ago... anyone with any ideas? WhiskeyTango 10-13-2002, 04:07 PM Don't have many ideas, worse comes to worse do a compression check, maybe pull valve covers and see if there's a bent pushrod. Maybe specify year, engine size, if it has EFI etc. If it's EFI maybe the o2 sensor is bad, not sure if Ford's have these though. Over time and deductive reasoning I'm sure we'll figure it out. Is it puking out black smoke? Maybe fuel starved? Vaccuum leaks? At night run it in no light and see if anything is arcing underhood Possibly wires on fuel pump pissed?? or whole pump could have taken a crap. bobbed83toy 10-13-2002, 04:14 PM its a 1985 bronco, with a 5.0 EFI in it.. it is puffing out a light white smoke.. smells like it is running rich.. very possibly could be either a O2 sensor or a EGr vavle WhiskeyTango 10-13-2002, 06:56 PM LOts of white smoke means head gasket. That would definitly make it run like shit. It will get smokier over time, The exhaust will smell like antifreeze as there is anitfreeze seeping into the cylinders and being forced out the exhaust. wes8517 10-13-2002, 11:16 PM check the timing too, the distributor bolt in my block has been known to back out under loads, and then your timing gets all out of whack, so i dunno, just check it! wes | |
