Map or MAF 88 IROC
I just bought this car last week, I do know the car sat in a garage for a couple years, other than that i do not know much. it is an 88 iroc vert 5.0. HO 5 speed. The car runs rough, seems like it is running very rich too. check engine light was on, bought a cheapo diagnostic tool, came up with codes 34 and 14. code 34 in the book said mass air flow circuit or map sensor. I changed the mass air flow and the code went away but it is still running badly, possibly worse. so, i went to NAPA and they showed a listing for a map sensor so i bought it. but does this car have one? do cars either have a map or maf? I cannot find the map sensor and am beginning to think there isnt one. the other code was 14 which is the coolant temp circuit, so i cnaged the coolant temp sensor, that did nothing and that code i still have. any suggestions? it seems to run well at steady throttle at like 3k, foot off the gas, stalls. please help.
