Ok heres the Deal..I have an 86 Ford Bronco 2. When i first got it about 6 1/2 months ago it ran great..but then about a month or so later i started having problems..The biggest being: When im driving on the freeway or on public streets where its stop-and-go its starts to smoke..when it smokes it looses all power and tends to die on my a lot. But when im on the freeway i just give it even throttle for about 30 seconds and it will stop smoking totally until i turn the car off then right away it starts smoking again..I have changed quite a few of the censors and i dont know what it might be..if anyone has any idea PLZ reply to this post cause im desprate..

Thanx

What colour is the smoke?

Black smoke is unburnt fuel
White smoke is oil
White steam is water

Sounds like it may be a head gasket problem but need more info:smoka:

86 Bronco would be a 5.0L?
