Hello! My '89 chevy beretta 2.8l 5 speed manual trans failed emmissions test (high CO, they say it means my car is running rich), so now I get to learn about diagnosing cars. I borrowed a diacom+ setup, so I don't have much experience using it. I've got a few questions: When I drive, the Engine Cranking Speed changes! What gives? Could Diacom be mis-interpreting the ALDL data? Also I never see the Park/Neutral Switch, 3rd Gear Switch, and 4th Gear Switch change. I
Well, I can explain the park/nuetral switch...being that you don't have one. However, some cars use that pin to monitor the clutch engage/disengage.
Also, I've heard of GM using Auto proms in the manuals... I wonder if that would screw up Diacom a little.
