A/C on - Erratic Idle
This is the first Louisiana summer since the installation of my headers on my 94. Yesterday while driving downtown, with the A/C on, the car begin to have an erratic idle at stoplights - stalled once. Restart and runs fine while moving with no miss or hesitation but would still idle erratic at stoplight even without A\/C on. Checked for vacuum leaks, MAP sensor, etc. - nothing out of place. Did find two loose spark plugs that I tightened. Started it this morning, idles fine even with the A/C on. Is it possible that the superheated air, due to the headers, under the hood may have affected the reading on the MAF or some other sensor when driving downtown?

Hoping the same thing. It just seemed odd the way it happened since it was extremely hot down here yesterday and temps were up! I could easily see where those underhood temps with the headers could induce false signals to the computer.
