Before I take the car to the dealer and get raped I figuired I would ask the pros here. Under load in 5th gear , anything past 1/4 throttle it has a real bad mis, if i downshift into lower gears and get on it, the mis is still there but not as bad. I know what you are thinking COIL, right, well, now it's starting to cut off if I let is mis for a few seconds, just dies, but restarts right away no problem. That threw me into a loop. NO OBDII codes. I follow a easy rule, start with the cheapest and go from there, replaced fuel filter, still doing it. I think I might have bad gas or water and or dirt in the tank. Also how common do fuel pumps give out on our cars. ?????????????????

As Quoted from NSTAG8R, "just bought a 2000 Gt Silver , Cobra r, 4.10s. suspension and exhaust work done. Working on stereo as we speak. I live in southwest virginia (virginia tech) wanted to see if there are any mustang shows besides Fun Ford Weekend in Bristol coming up. By the way, dreamed about owning a mustang since I was 7, now I'm 25 and i LOVE MY PONY"
Amazing what a little search can pull up! All we need now is miles...but its safe to say OVER 50K. Could be the fuel filter since it seems to be throttle related...also could be spark. Change out the plugs and filter and see if that help...also clean the MAF and air filter.

the fuel injector in it are orange which do not look stock to me
I am putting it on a scope and watching the tps voltage right now , changed fuel filter, since the hesitation is low rpm with load I have narrowed it down to a ignition not fuel problem. If anyone can tell me what aftermarket fuel injectors were orange that would help me tremendously. I appreciate all the input.

This sounds almost like what mine is doing.
If I am in 5th gear and try to accelerate it kind of sputters, but never cuts off. If I downshift and get above 2200 RPMS the problem goes away.
Ford just replaced my cylinder head since they f-ed up a plug job and I blew a plug, so now it looks like they f-ed something else up.
Let me know what you find.

man ive been running great with texaco fuel. no sputtering or hesitation.
try switching fuel brands.(hopefully its as simple as that)

VOLTAGE DROPS 4 TIMES ON IDLE TO 5K REV, TPS SENSOR IS BAD, I ORDERED ONE. I hope this is the only problem, the voltage drop was not visable on a voltmeter i had to have a graph scope on it to see the sudden spikes. Makes sense since the fuel will be shut off momentaraly since the pcm has no clue where the throttle is. I have one on the way I'll let you know if this solves the problem. Thanks for all your advise, I'm a Service Manager at a Honda dealership so if anyone needs Honda advise please let me know
