Map and maf sensor issues

[Black_cirrus]

So I'd check the ground and power to the maf, if you have a multimeter. I don't know the wire colors but can try look them up tomorrow at work. My gut guess is a bad ground or weak voltage to the maf. but a maf issue would change the fuel trim on both banks. What are the trim numbers. And yes the map sensor readings are the same as the TBI I was working on this morning 10/28..

Yeah for some reason I was thinking a map would read vacuum. map is right. thinking i have dirty contacts on the maf still reads the same with the engine off but is only around 6.5 at idle not 8.0. all I did was spray them with some electrical parts cleaner

Clean the MAF, if it is dirty I believe that can cause readings to be off. Make sure it's actual MAF cleaner though, it can't leave residue.
