Message I've done some searching, but don't really see anything like my problem. The car has absolutley zero power when trying to drive. Put the car in neutral, step on the gas and it all but dies while trying to maintain 1,200rpm. I keep pressing the gas and it slowly creeps up to 3,500 rpm(stumbling the whole time) then suddenly shoots up to 5,000rpm and will run like a top if I hold it there. There is no idle issue, nor a starting issue. I've replaced the MAS and the fuel pressue is 38psi. The PTU was replaced about 13 years ago under the recall. What would you guys be looking at? I hate to throw money at sensors like the dealer$hip.
