My 96 mustanggt is stumbling terribly when accelerating, particularly when you hit it hard. does anyone know what this may be?
It may be coincidence but it happened after we were messing with the throttle position screw as it idled so low.
I first thought it may be ignition system but i have all new wires and plugs and checked them, does anyone know what it may be?
or is it just the screw is now in the wrong place? would that have that affect on accelerating.... its like a stopping sort of effect, it really stutters when you hit the gas anywhat hard.
Thanks guys

ive had the same problem, replaced fuel filter and pump,tps,plugs wires,maf sensor,coil packs,o2 sensors and new computer,2 ford mechanics 3 local mechanics and myself cant figure out whats wrong car has never pulled any codes, feels like fuel starvation or timing retarded severely but nothing comes up on scanner
well being that u were in the area of the spark plug wires make sure one isnt broke. i had a issue with mine about that once bought new wires and was good to go

it seems like nobody ever checks out EGR, evap, or any of the emission systems. They can too create the same problems you are mentioning if not working properly.

A bad TPS is very common in Mustangs especially after 50k miles. I would recommend changing that first. Before you go changing out a lot of other stuff.

i have an idea, instead of being a parts changer and wasting money, diagnose it and fix it correctly the first time.
