1994 chevy truck 4.3 vortec engine, 5 speed. 150psi compression No check engine light on, yes it works.
Truck is offroad plow truck only.
Truck is running rich, mostly seems like the passinger side not firing. I can take off 2,4 and 6 wires and no change in engine. Smoke smells of raw gas coming out exhaust. truck barely moves. wont hold idle anymore.
Changed: plugs, wires, temp sensor, dist cap and rotor.
I have found posts saying lines in the plenum maybe leaking.
WHat can cause this to run like this ?
I'd like to know is if this truck has those lines inside the plenum? Or is this just a regular intake ? are the lines under the intake or just the throttle body ?
Here is pic of engine, throttle body injected
