So ive changed the battery, plugs, wires, and coil on my 90 bonneville. When i start it and let it run for a few minutes it will start to stumble and eventually stall out. Unpluggonf the maf allows the car to run at a bit higher than normal idle while in park. When in gear the car idles around 1000to 1200rpm. However it runs fine. Am i right in thinking my maf is bad? I tried to clean it and it didnt help nor hurt the issue.

hi, if the part is cheap, then I would replace the maf - did you check the wires and connection?

I'd say yes, replace - running well unplugged is a good indication that its wonky
