What is causing this?

Maintenance/Repairs

Recently it acted like it might be tied up. a few days later i tried it again and it would turn over, but not start. a few days later i tried again and the same results, each time , the more times i cranked it, the less it wanted to turn over and it would act like it was tied up and would not turn over. Today i installed a new IAC & TPS and it acted the same. I tried the TPS installed incorrectly (where it held the throttle open a little) i know this is wrong but what the hay, nothing worked so far! Well it did start, high RPM and climbing fast, no foot action on the gas pedal. I turned it off and tried again and the same results. I installed the TPS as it should be and it acted the same (Tied uP)
