Yep, DTC 7 = TPS

Make sure the MAP and TPS plugs are not mixed up. Check the TPS voltage. It should be close to 0.45V at closed throttle [this value MUST be below 0.50V] and close to 4.5V at wide open throttle. There should also be no 'dips' in voltage or dead spots [0V reading] through the entire opening of the TPS. It should be a smooth increase in voltage from closed throttle to WOT.
