I think its my throttle position sensor but not sure

Hello, the clues are really inconclusive without performing needed testing. A throttle position sensor is a guess, and although it could be related, you could also have a transmission issue or an air intake issue or a fuel control issue -- it's all a guess without testing. So, get some professional testing and go from there. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
