Throttle Body issues!

[Ricardo]

03 Tahoe I'm getting a reduce engine power code. Changed out the throttle body for a new one had the throttle body codes deleted because it was rev up to high got it all fixed up drove it home no problem what so ever next day turn it on drove it about a mile and again reduce engine power came on!! Already changed out the throttle body 2 times and still getting the same codes!

[Ricardo]

Code #p1815

Could be MAF sensor, throttle body plugs or wires, etc, Daniel (d1nman) had that code and changed all of previously said stuff and it was fine after
