ok, been trying to solve this for like a week now, here is the problem:

Whenever accelerating from a stop light the car will jerk ( similar to hitting the gas then letting go and then hitting the gas again) a lot until i back off the throtle to like 2%. And it doesnt do it all the time, like this morning it drove to work fine, but on the way back it was doing it. And keep in mind that this is happening when i am not boosting at all.

Checked for boost leaks, changed spark plugs, checked fuel pump & filter, i also ordered a new set of coil packs and wires, but in the meantime i switched mine with the ones from my buddys lancer and it is still doing it, i am still changing them anyways my car has almost 50000 miles.

Anyways, does any body else have any idea what could be causing this?
Could it be a really badly worn out clutch? it always seems to happen between 2000-2500 rmp which is where i launch at.
Im just trying to think because if it were misfiring it should be giving me a trouble code, but nothing has come on yet ...

Any input is greatly appreciated!

Does your car idle normal?

yes, everything else is normal, once i get crusing it is fine, unless i try to hit the gas then it does it again but less noticeable

yea it sounds like a bad mas, if its not that, more than likely its a boost leak.

ok, disregard i have found the problem, after staring at the engine for a minute trying to think about it i noticed my oil catch can was really dirty, so i pulled it out to clean it and behind it found one of the tps wires all cut up by the oil catch can ( which i installed long ago "temporarily" in that area ) so i fixed the wire up and relocated the catch can to a better position, everything seems fine now.
