Pull the codes, I suspect you will get some related to one of the pedal potentiometer's signals being implausible. These codes do not light the check engine light. The pedal has 2 pots, one reports twice the voltage of the other. If the pots or wiring causes this to get out of range, the car goes into limp home mode. Make sure the second plug from the top is clean and seated properly on the DME.
