I have an 04 GT, with 92k.
I purchased the car used. Here are the known mods
3.73 gears, cammed, 78mm TB, Off road H pipe, flow masters, tuner.....
Have had the car since April. The only problem with the car up until now is when I turned the A/C on the idle dropps below 500rpm and would have a hard time idleing.
2 weeks ago I filled up and that's when the problems started. I thought it was bad gas, but the problem is still there with the new tank of gas and after running seafoam through a tank of gas.
The car seems to idle fine, but has a very noticalbe hesitation/stutter under acceleration. It will smooth out some when the car warms up, but the stutter is still there.
I have cleaned the MAF and have driven with it unplugged, but the problem is still there.
I have cleanded the IAC and TB.
I replaced the fuel filter as well.
One thing I did notice is after I cleaned all these components, the car really ran well, I assume it was because of all the spray in the TB and IAC I used, but once all of that burned off the hesitation/stutter returned.
The car idles fine and revs fine,...it seems that from about 10%-50% throttle the hesitation happens, but anything about 50%-WOT it runs strong.
Maybe bad TPS?
Any ideas what I should check next?
