OK, I've spent hours searching threads before I posted this. Between 1500-1700rpms while lightly on the gas peadal the car feels like it surges or like something is holding it back then letting go. Under any other throttle position or rpm it's perfect. It's a 95ss, cold air and flows, thats it. I've already replaced the fuel filter, treated the gas, checked the egr, replaced the wires and plugs(not fun!) removed and cleaned the throttle body and had the local shop run the codes (no codes showed up) The car runs perfect except for that. I parked it for a week and next thing you know this problem arrises. Any and all help is greatly appreciated.
