I have a 1992 chevrolet lumina with a 3.1L and it is throwing engine codes 23 and 44. Here's what has been done. New lower intake manifold gaskets, upper plenum, spark plugs fixing leaks and doing tune-up. I didn't have the car long enough to know if it was throwing codes beforehand as I bought it and went straight to work fixing the problems. I replaced the IAC already. What could be going on? Thank you
have the same problem?
