You may want to check the speed sensor of the car. IT should be located in between the engine and the transmission. At high speeds if the ecu would not get any feedback from the sensor it would normally light up the check engine light.

Do you get a check engine light? Generally this problem can be caused by a leaking injector or the "cold" enrichment (modern version of a choke).

Check engine light


Take it to any Auto Zone, Checker, or similar auto parts store, they will have the right adapter for your car and do it for free. Some auto shops will also do this for free. It will be a plug under driver side dash that you hook the computer up to.

Engine runs rough after about ten minutes /idles really low


Just trowing some suggestions out there, but, I would check the idle air control valve (solenoid) or the throttle position sensor. If they check out then my last guess would be the map sensor or the vaccuum to the map sensor. Hope I was able to help. Best wishes.

Service engine soon, SLIP, TC OFF LIGHTS ON


I had the same indications on My 2000 Maxima but the engine was also running rough . I replaced the number 3 cylinder ignition module and all of the spark plugs and all of the error lights are back to normal I had to reset the check engine light by disconnecting the battery for about 15 minutes.By the way my car has 253,000 miles on it so if you have a lot of miles on your car you might want to check all of the ignition modules so pull your spark plugs and read them they might tell you where your problem is .
