Hello all
I have a 2003 Mach 1 that stalls when AC is turned on when the car reaches its normal temperature. IAC, MAF & TB have been cleaned also checked for leaks and all clear. I have also changed the O2 sensors upstream. The Mach also stalls at times in stop/red lights AC off.
After the built the Mach would stall here and there while slowing down or complete stops obviously needing a tune. RPM’s at idle would be around 8-9 roughly, now just before the tune my brother swap the battery and connected it backwards for a good 2 seconds. Lighter and stereo fuse are the only fuses that blew but the Mach didn’t feel the same. At idle it would now be at 5-6, it would struggle more to stay on. I got the tune done but the stalling is still there I feel it stalls even more after the battery incident.
