Check the wires at the connector to the TPS by gently pulling on them, if a wire is broken, the wire would stretch some, then the wiring connector would have to be replaced. Also check for vacuum leaks.

Thank you for that. But I took off the air tube to the tb and it started to Idle better the min I put the tube back on it shot the idle right back up. Could it be the mass air flow sensor needing cleaned?
Yes, could be needing a cleaning, or replaced. Make sure and use MAF spray cleaner to clean it with.
