Hello! Newbie here.. Read through quite a few posts but I'm just not sure(also not a gear head).. I have a 97 Cherokee sport that has had some weird bugs as of late. Recently I've changed the safety neutral switch, fuel pump, spark plug wires, rotor & distributor cap, and deleted the stock air filter box and installed a after market cold intake. Well i still have a problem that I can't figure out.. Has a hard time idling, will die if revved and immediately let of the gas, seems to have no horse power.. Gets worse the faster I try and go. I took it into a dealer once to see if they could pinpoint it (of course they tried to give me a thousands problems).. Here is the main diagnostic: "Scanned computer. Had code P0121 T.P.S. Does not agree with M.A.P. O2 sensor skewed from exhaust leak." Any thoughts as what i should try first? Since I'm getting low on funds :D

Any input would be awesome!
Steve~
