The Car is all stock.This is what i changed:
First I ran Seafoam, then I changed the Oil. (The car was doing this before I ran Seafoam).
O2's sensors, wires, plugs (twice), Fuel filter, replaced MAF 3 times, Made sure MAF was cleaned. Put 93 octane gas from 3 different gas companys thinking that I might have a bad batch of gas, I did the injector cleaner stuff.
The car idles beautifull. When you drive part throttle it runs perfect. Then when I WOT, about 3500 to 4200RPM it stumbles or hesitates. Sometimes you can hear a faint poping sound. This happens when the car warms up. When the car is cold and you WOT it, it runs fine. On one or two rare ocasion it stumbled or hesitated but it does it the most when the car is running at normal temp.
This car is my Daily Driver and its really driving me nuts.
