79 mustang that doesn't work well

nadia · 03-01-2001, 10:16 AM

I just bought a '79 Mustang that has ran and still runs like crap. The engine seems to be running extremely rich, white smoke pours out of the tailpipes, and make my eyes burn from the raw fuel. It wants to stall while running on the road, in other words it's undriveable. I has an '87 5.0 with speed density and T-5 (it was converted). I ran codes but it comes up OK, I changed the ignition module, replaced the MAP sensor, and pressure regulator. What could be wrong?!

Lots of white smoke in the tailpipe, eh? Almost sounds like a blown head gasket. Have you tried running a leakdown test or a compression check? That's the first thing I'd do.

Sounds like a blown head gasket. that'll cause the white smoke and cause it to be undrivable. A couple of things you can check if you have the resources is compression/leakdown, check for bubbles in the radiator, and if there's coolant in the oil (or especially if it looks like chocolate milk). I wouldn't drive it anymore until it's fixed if i were you.
