MASS OR VOLUME AIR FLOW CIRCUIT LOW

1998 Pontiac Bonneville

Engine Performance problem
1998 Pontiac Bonneville 6 cyl Two Wheel Drive Automatic 158000 miles

We replaced the mass air flow censor as it indicated that was the problem at the car place where we tested it, but now the car will not stay running, you can't let it idle. Any ideas as to what the problem is? We are at our wits end here.

Try cleaning out the IACV and test its operation. If you dsiconnected the battery prior to yu replacing the MAF sensor-could be that it needs a computer relearning process.
