I have an 1988 5.0 at with maf and I keep getting a code 19 and 14 in the koeo. I replace the ign module rotor plugs, and wires and it help the hesitation problem but still get the check engine light and a rough idle. The car is all stock but bbk equal length headers and a bbk highflow h-pipe with cats and a fenderwell air intake. I don't know what to do I can't find any test procedurs to go through to help me. Also the brake booster leaks on the backside into the car and makes a hissing noise, but it does effect the way in runs i think because I sprayed carb cleaner on it and the rpms did not change and the brakes work fine.
