p.s. resetting the ECU did not work. the check engine light is still on and the speedometer "jumps" or just doesnt work at all. the odometer, trip meter, signal lights, temp, and fuel gauges work fine on the cluster. any suggestions? i'm most likely going to take my car into my regular mechanic to have the install checked out and get the engine tuned. i'd just like to have the speedometer working before i take the car in next week.
