i have a 2003 evo VIII, when i am going down the road cruising at 3-4000rpms, my car will suddenly start missing. If i let off the gas and get back on it. the miss will go away and then come back. It does it i would say 90% of my town driving. It only does it when i am in the 3000 - 4000 range and if my foot is steady. Once the miss starts, i can flat foot it and it will miss all the way to redline. But once i let off the gas, and get back on it. it goes away
just so everyone can under stand what i mean by the miss, basicly when it starts the car sounds like a WRX or something of that sort.
So far i have changed, Spark plugs, Wires, Coils, Mass Air Flow Meter. and done a boost-leak test
The mods to the car are 3" TBE, injen upper ICP, greddy Profec-b II, 3" Gm Maft. other then that the car is stock.
Any idea's would help greatly!
