03 Regal runs good with MAF unplugged
I have a 2003 Buick Regal that my daughter drives. Monday she put gas in it and Wednesday it died in rush hour. Seemed like it was starving for gas so changed the TPS on some advice, no luck. Changed the fuel filter, ran for about two miles, died at an idle then wouldn't start. Under the wrong advice from the local parts store changed the fuel pump because it showed 50 psi and they told me it should be 85 psi (they were wrong). Went to load it on a trailer to haul it home and on a whim I unplugged the MAF sensor and it ran fine. Drove it the eight miles home, plugged in the MAF sensor and it loaded up with gas and died. Cleaned with MAF sensor cleaner, no luck. The only time it throws a code is when it is running and I plug the MAF in (low voltage). No codes when MAF is unplugged. About everything I have read says the MAF is bad. I understand that by uplugging the MAF I am bypassing some other important readings such as O2 sensors. Should I look at something else or bite the bullet and replace the MAF? Any help is greatly appreciated as I am not a mechanic. We are $360 dollars into this and it still is not fixed.
