when cranking check engine light comes on and warning horn. engine will idle but go above idle. Stuck in SLOW mode.

pulled codes 15 and 35. Any troubleshooting advise. I have heard change the TPS sensor and other say send in your ECU.

May have a wiring problem since throwing both codes.

okay i checked the wiring for the tps sensor. all three wires are good. I installed a new oil pressure switch and the code 35 is gone. I still have code 12 and 13. installed a new tps sensor and still same codes and same issue. rechecked wiring it is good. Only thing I can think of is the ECU. Since its sends voltage to the tps and receive voltage. What do does everyone think. I need help and fast for any other ideas. I have a tournament in 3 weeks. Should I send out to DFI for repair or just get another ecu of ebay that is in good working condition.

That would be next step, if TPS and wiring checks good.
