i have a 1998 pontiac grand prix gt 3.8litre. ihave a p0102 code. I disconnected the wires to the MAF and the other device between the air filter and the MAF and still chuggs and stalls periodically. the p0102 is the only code that i can pick up with the obd2 code reader. the wires all appear to be ok. i have not yet checked the voltage on the maf wires, or bending pin 85 on fuel pump resistor. any thoughts on what it would be... cps?
