P0122 Throttle Position Sensor/Switch A Circuit Low Input is what im getting from my check engine light... this happend after i put the stock tb/plenum back on my car.... could the sensor just finally of went bad or will that small amount of -(+) in voltage make my car idle like crap? Its pissin me off like seriously it idels anywhere from 500-1G so advice/help would be nice. Thanks Matt

Thank god they are only 30 dollars and if that dont fix it then what would be next on the check list wires bad?

That will more than likely fix it. Everyone I've had that problem with was the tps

Well i got a new TPS and that fixed that code now im reading lean from bank 1 sensors 1 and 2. I left my tune in the ecu since i have gears and i didnt wanna get any unwanted tickets. Will the tune make it run rich/lean? i have a JLT ram air and 78TB/plenum so im thinkin it would. Either way the idle isnt as rough but its still rough. I'm lost as to whats making it do that.

Is there a vacuum leak anywhere?
