1996 park ave with 150000 miles. Stuttering and stumbling, idle problem. Gives a p0102 code low voltage to maf sensor. Changed maf no help. No other codes. Cleaned idle control valve no help. Changed plugs and wires no help. Votage at pigtail on maf is pink wire 12volts on yellow wire is 4.5 volts. Does anyone know what the volts should be? If yellow wire should be higher how do I fix it. Thanks in advance for help, I am usually pretty good on these but this one got me stumped. Shalagre

Your voltages sound right. I would start by checking for a vacumm leak. Check the gasket between the supercharger and the lower intake manifold. Pay close attention to the front(under the drive pully) they have a tendency to suck that gasket in and cause that code. That will also cause it to idle incorrectly and chugg.

Hope this helps.
