This is my '86 Chrysler T&C I did a T2 conversion on.
It runs nice and smooth for a couple minutes, then is gets rough, and has a frequent miss a cruise speeds. If I accelerate hard it seems to run fine (other than it won't boost as high as it's suppose to).
Plugs, wires, cap and rotor are all new.
OH, the wideband o2 needle will jump up every time the engine misses.
Any idea what may be the problem?
