Anyone out there having a low speed surging problem with their 05 Mach? Trying to run low speeds like 15 to 30 in town or behind any traffic is like riding a bucking bronco. I has a good belt and everything is well ajusted.

Do you have the 05 ECU program or did you get the 06 program in stalled? and if you have the 06 program,Did you get the 06.5 update program for start up installed? You are experiancing a run lean condition.Its like its running out of fuel than it takes off again,it makes the sled buck at low rpms.this can only be rectified buy hooking up to the BUDS and have them check to make sure your TPS has been set properly,and check the timing is correct. Have the rave cables checked to make sure you have some slack in the bottom cable and that it aint to tight.
I have found having the dealer add 1 degree more timing to your exsisting timing makes it run cleaner and more throttle responce,It seems to run and accelerate more crisper,smooth.

Tell me more about 06.5 update for start up. When did this update come up? With the dealers I have to work with I need to be educated before I take it in.

You would think I would have paid attention to the rpm but I didn't
