Hey Scotty if there any way that the throttle position sensor can make my truck shift hard? I have the 302.

The check engine light comes on and goes off as it pleases, when it's on and j get on the gas it shifts hard and at a high to. But when it's off I can floor it and it has all the power in the world and shifts like a brand new truck. But after I drive for a while (10-15 mins) it boggs down and I basicly have to floor it for it to drive normal. Of there is anyway you can help PLEASE LET ME KNOW. Thank you

they do that all the time if really bad, computer uses that for shifting info too

So the TPS would solve my problem?

It's a 1995 Ford Bronco forgot to mention that
