My car doesn't seem to go any where when i completely step on the gas, it only really goes anywhere when I step on the gas about 30%. I already replaced the knock sensor, ecu, spark plugs, replaced my clutch, Fuel filter, cleaned my fuel injectors, and checked my compression on my engine and it was 160 on each piston. I also have no check engine light, but i do know my tps isn't working but I doubt that's the issue because my car would still accelerate even with a crappy tps and i've been having this issue for about 5 months now. I also have no vacuum leak. I love my 240, but this has really been making me go nuts.

Mass air flow sensor might be bad.

My mass flow air system is solid. I already checked the ground for it and my rpms don't bog. I guess i'll just take it to a mechanic's shop for them to clear up what is up with it.
