Re: Beware Of The Bronco 2 Curse!!!!!

This sounds like what happened to my 87 Bronco II about 15 years ago. I would be driving down the highway after the engine was fully warmed up and it would sputter and cut-out until it would come to a complete stall. Would turn on engine after several minutes and start the whole process over again. It was the ignition module!! When I had that changed out it never did that again and has been running great ever since, 380,000 miles later.

Re: Beware Of The Bronco 2 Curse!!!!!

Hey everyone, so I had a similar issue with my 86 Bronco 2, the way I fixed my truck was by bypassed a fuel filter underneath the driver seat. I think there was a loss of fuel pressure and after this repair, I have not had this issue since (5 months).

Re: Beware Of The Bronco 2 Curse!!!!!

white smoke is usually water, is oil milky looking or bottom side of oil fill cap white? might also want to run a compression test. think the 2.8 and 2.9 had head gasket and head cracking issues

Re: Beware Of The Bronco 2 Curse!!!!!

DEFECTIVE EGR VALVE IS THE PROBLEM : )
I have an 87 Bronco II with 2.9 V6. Was having same warm up and stammer and sputter with loss of power. I did everything - plugs, wires, IACV, TPS, etc.

Had hunch it was a defective EFR valve. Tested the problem by placing a metal plate (made from cutting up an aluminum pop can) between EGR valve and intake. This prevented any exhaust gas being able to be recirculated back into the intake improperly. VIOLA!! FIXED PROBLEM!!

Stupid EGR was stuck open and choking car with too much recirculated exhaust gas. This was making the car sputter due to lack of oxygen and the car' s computer was doing its best to compensate the proper fuel air mixture but just ended up running way too rich and stinky.

Good luck.

Re: Beware Of The Bronco 2 Curse!!!!!

Has anyone checked. The fuel reg. It has a rubber diophram in it that can go bad and srrart to dry up and leak fuel. Iit happened to me. It spit out black smoke and raw fuel ran like crap. Had it towed into my mechanic and he knew what it was right of the bat. It toasted the cat. Converter but that was an easy fix. Im not sayin this is your problem but it is the only problem i had with my 86.

Re: Beware Of The Bronco 2 Curse!!!!!

Shot gunning pArts and sensors to a problem is amateur at best. Bronco 2 tfi ignition systems were notorious for multiple problems ranging from over heating to losing ground. Another problem was the pins I. The plastic fuel pump connector had plastic melted contacts these contacts were prone to breaking especially 86 and 87 with dual pump set ups. The pins would push down into the tanks and not plug into the connector.
