man im reading this and its the same problem as my hatch. i got an ls in mine also. mine is running ridiculously rich. i hit the gas slowly and it bogs down. and when i take it up to higher rshared_pm it feels like its running lean. im sure i dont have the tps and map sensor mixed up. and the only code im throwing is the map sensor but its a brand new sensor i wouldnt kno why it would throw out that code. maybe its a ls in a ef thing lol
