1987 Chevy S-10 6 cyl Two Wheel Drive Automatic
1987 Chevy Blazer Vortec 4.3 engine.
Replaced: distributor cap, plugs, plug wires, coil.
Runs rough when in gear, but idles fairly smoothly and revs well with tranny in park. Sometimes blows a bit of black smoke. I can smell unburned fuel heavily in the exhaust.
Is this a pickup coil issue?
have the same problem?
