Default 85 rough / no idle smokes

The car stalled out once while diving. i limped it home. since then I have replaced.

fuel filter
distributor rotor "the old one was found to be loose when diagnosing"
injectors
hoses
manifold gaskets
pcv valve
plugs and wires

The car will start but requires that you use the pedal. it will not idle on it's own you must throttle it. It smokes while running.


Any ideas

Thank you
Eric

Have you checked fuel pressure?

White smoke or blue/black?

How may miles on the car? Cat new?
