I just replaced my TPS on my 1996 cobra cause i bought it and the guy before me installed a nitrous throttle sctivation switch which splice into one of the wires and when i got it it was not putting out the correct voltage at idle and WOT position so i bought a new sensor and it fixed it the voltage is now corect at idle and WOT but it has no power til 3500 rpm...so do i need to take it somewhere and get it calibarated..i bought the TPS from oreilly's auto parts...what do yall think i need to do???
