tpi? try the TPS. Sometimes they get gumed up and don't report to the computer right. Happened to me once. If there is a parts store close by, sometimes some parts stores and test them.

the connection must be tight and clean.. Also check the mass air flow sensor, that might also be giving you problems.
Most of the time the tps inside goes out. It doesn't read right.
