My car runs great but when I get on the highway and drive for more that 25 minutes the rpm start going high and low and my car starts jumping. The odometer stopped working and the speedeometer stopped also any suggestions.

Hi ilsiddiqui02,

Thanks for the donation.

When the odometer and speedometer both stops working, it should be the speed sesnor that is faulty. Get it replaced.

When the speed sensor is not working, the trans would shift irregularly as the speed signal is not received by the PCM so it does not when to accurately shift.

As to the surging when engine has warmed up, the following things could cause it.

1. Vacumn leakage at the throttle body. Check for disconnected or leaking hose.

2 Idling speed set too high.

3. Faulty EACV/IAC or its coolant hoses are clogged. Low coolant level in radiator could also cause this.

4. Faulty MAP.

Is the CHECK engine light showing?

Hi ilsiddiqui02,

If the code is showing the speed sensor, then replacing it would solve the problem.

Is it rather easy to replace it.

The sensor is attached with 2 pcs of 10mm hex bolt to the trans meter gear assy located just below the thermostat. If you remove the air intake hose, it would be easy to get to it. Just unplug the wire connector and remove the bolts and it will come out, take care not to drop the pin inside when installing.

If the sensor is something else, let me know the code and I will direct you the way to get it solved.
