2007 Yukon 5.3 rough/sputtering idle while in gear at a stop. Runs great while accelerating. Last week it went into reduced power mode with code P2135 (wrong reading or voltage correlation issue between throttle position sensors) I turned the engine off then back on and it ran good. Did this to me one more time and ran good again. I cleared the code and haven't an issue with that again. It's had code P0442 small EVAP leak for a few weeks. I also cleared that code and it just came back on 5 days later. I have cleaned the throttle body (it was real gunky), cleaned the tps, MAF & MAP. The only thing that appears off in live data is both LTFT reading between -14.1 to -17.0
Any ideas on what I should check next?
