87 Gn turbo ~ Problem

Hey everyone, I have an 87 Sn 3.8 turbo~ Its running funny~ I have a Maf too low code~ when the car warms up and you put it in gear it will fall flat on its face... I tap the maf and it will go from 6kg to 22 to 255 to 3, stall stumble... I believe this is the problem... but at idle it seems as if its running on 4 cylinders~ can it also be in the ecu~ coil pack or ing module? thanks... Greg

Bad MAF sensor, If you have the money I would suggest a LS1 MAF and a translator. Berter metering of the fuel= better performance/fuel economy. As for the coil pak, yea it could be a sign but, with your MAF bad your car relies on the calpak to keep it running (Real rich fuel maps.) You could of fouled some plugs. I would reccomend getting your MAF situation figured out before you do anything. a bad MAF will make these cars do alll sorts of goofy crap.
