I've got a 84 pretty much stock, with a condition where it's hard starting and doesn't want to run when it's cold and even once it warms up it won't idle at the 700rpm it should. It fluctuates but is usually around 900-100 in drive.
I've replaced all of the normal things for a tune up, o2 sensors, cleaned the TBI's, air filter, gas filter, plugs, wires, rotor. I had to put a new water pump in it and the pressure told me real quick that I needed a new radiator.
Of course, oil change and filter. Nothing but top of the line parts. No skimping at all. Exhaust is fine (all stainless 2 years old, gutted cat, Flowmaster 50's). I'm planning on replacing the gutted cat with a hi-flow cat in the spring but that's not the problem.
I put an '85 Delco fuel pump in it 2 years ago and the fuel preasure is fine.
I did notice though at an idle I'm getting a constant spray out of the injectors even though the butterfly's are closed and the gas is just kind of laying on the butterflies?
All that's done and I still have the problem described above. I'm thinking the CTS may be the problem. I suppose it could be the 22 year old ECM too.
Ideas?
