CADILLAC FLEETWOOD ENGINE PROBLEM

1989 Cadillac Fleetwood • 83,567 miles

I have an 89 Cadillac Fleetwood Brogham RWD. Once it warms up mid range 40-45 mph lack of power, then when letting off the gas idle gets so low the stop engine light blinks and comes on and off. I put it in nuteral to speed up the idle to keep the stop engine light from staying on.

I am planning to install a new exhast system could it be a plugged muffler or Cat convertor?

Has new wires, Dist. Cap, Rotor, Plugs, PCV value, Fuel Filter.

Try pulling code/s from the computer and check/test the idle air control valve, throttle position and manifold absolute pressure sensors-
