91 Oldsmobile cutlass supreme runs rough?
Troy B asked:
I have a problem with my 91 Oldsmobile cutlass supreme 2.3 quad 4 motor. The motor runs rough and I replaced the spark plugs, boots, ignition module, fuel pump, fuel filter, air filter, crank sensor and still runs rough. The check engine light comes on and the code is code 26 which is a Quad driver circuit? What is the quad driver circuit and what is it, auto parts store cant get me one either. when I first start it you can smell strong gas fumes and the engine shakes.
Any help will be greatly appreciated.
thanks in advance Troy B.
I have also went to the salvage yard and got a used ecm, (computer) The computer had the same part number so I didnt change out the prom.
someone please please tell me why it does this.

Injectors could be worn out and not atomizing the fuel in the combustion chamber causing a misfire.
