Reduced power message
Replaced the tps on old throttle body but still getting reduced power message. Bought new throttle body and the only difference between the is the tb engine shuts down, with the new tb the engine continues to but sputters. I’ve relearned to tb in both cases, any suggestions?

What trouble codes were you seeing if any that made you decide to replace your TPS sensor if you do own a scan tool ??...where did you buy the new TPS sensor ??...if Amazon or Ebay I'd be suspicious as there are many counterfeit parts there...do you have a scan tool read the TPS voltages??...if not they can be read with a DVOM...unfortunately there are no silver bullets diagnosing these REP issues.
