The problem started after a new fuel filter. After the new filter the main pump started whining and making all sorts of noise so i went ahead and replaced it thinking i somehow shorted it. Since then, ive replaced the knock sensor, coolant temp sender and tried a different fuel pump relay with no luck. I took off all my intake hoses to inspect, and cleaned out the intercooler. There seemed to be a sufficient amount of oil in it although its only been a couple months since i cleaned it last. I know the turbo is spitting SOME oil into the intake but i dont think its affected the cat just yet. It needs a rebuild. All plugs and wires are under 3000 miles and i have new gaskets all around, engine was running great before this issue. Its almost like at 1000-2800 rpm in first and second the engine falls flat on its face and acts like its receiving zero fuel, i cant be certain but im sure its misfiring. Once about 3000 rpm in any gear it has no problems, boosts normally and responds well.
Could i be a bad 02 sensor or possibly ignition coil? AMM or FPR? Any suggestions welcome, the local shop wont take a look since they dont have any Volvo experience.
