85 Camaro won't idle without gas & running rich after battery disconnect

10

Asked by Earl Apr 19, 2017 at 04:50 PM about the 1985 Chevrolet Camaro Z28 Coupe RWD

Question type: Maintenance & Repair

I recently bought a 1985 Z28 Camaro with the TPI
(Fuel injected) 5.0L 305 in it. The car was tunnjng
fine until I disconnected the battery. Upon
reconnecting it the car started dying at start up and
refusing to idle on it's own if I didn't give it gas. I
figured a sensor problem was the case so I
removed and cleaned the:

- Maf sensor
- Throttle Body
- Idle Air Control Valve

After putting everything back, the car now is
experiencing the same idke problems but is also
running rather rich and putting out a lot of black
amoke from the exhaust. I should also mention that
trying to apply too much throttle will occasionally
stall the engine as well.

I am trying to figure this out but am torn on what to
direct my attention to. My guesses are problems
with: MAF Sensor, Throttle Position Sensor, EGR
Valve, or the Idle Air Control Valve.

Any experience or advice?

I've tried driving it and it will stall when coming to complete stops if I don't give it gas. Also, upon accelerating from a stop there's a noticeable absence of power, and I can feel the transmission shifting hard/not wanting to shift so easily

If the engine is holding back when you try to accelerate, may be a plugged catalytic converter.
