New guy with loping problem...

[Eph6vs11]

I know you guys have probably heard this before... I have search the threads and did not get what I was looking for.

I have a 2000 Mustang GT and it has this loping problem... It seems to be BAD when I have the A/C on. It does get to the point to where I can be at a stop light and if my foot is not on the brake REAL good I will lerch forward a bit.... Any help???

What do you have done to your car? Dump the codes first. See what you get.

is your loping = to a surge? If so you may wanna check your AC coolent level. I have noticed when the AC gets low, the car tends to surge every couple of seconds when the compressor cycles. Try adding some refrigerant and see if it doesnt solve your problem.

The car is pretty straight I have kept it stock so far. I think I have finally talked my wife into a flowmaster exhaust....

Cool... I will dump the code and add coolant.
