Check your +5 volt reference and grounds.

Easiest way is to unplug the TPS sensor and check for 5 volts to the block and to the correct pin in the connector. Do the same thing on your MAP sensor. If the +5 volts is being pulled-down from something it will screw-up everything! A bad ground will also wreak havoc.
