91 lumina 3.1. Car misses and hesitates, tune up not that old, recent new injectors, cleaned iac, egr. The car also idles wierd when cold, high uneven idle and will die a couple times. When its warm, this goes away, but the car still misses and hesitates. I got a trouble code 44, and 45. Both lean exhaust and rich exhaust. How can I get both codes? I have also checked for vac leaks, and did a redneck smoke test. SEEMS to be no vac leaks. Also. The engine cooling fans don/t come on at all. The only time they come on is when I do the paper clip in the obd1 terminals. Any help would be appreciated! Thanks. Mike.
have the same problem?
