I have a 1992 GMC Safari SLE 4.3L CMFI Motor 2WD 201005 Miles that is blowing out black smoke, has a very rich gas smell and has went from 22 MPG to 6MPG. I did a code check and got one error Code 45 rich exhaust, I cleared the code and drove about a block and rechecked
and recieved no code. This is what I have done to try to fix it, I have replaced the oxygen sensor, coil, distributor picup, rotor and cap, engine temp switch, oil sending unit, and I did a fuel pressure test that was within range.
Anyone have any ideals?
have the same problem?
