under the driver seat is where the ecu (computer) for the engine.
slide the seat all the way forward and look under the seat from the back. there is a cover over the ecu and at the back is a small square tab that can be flipped down. flip it down at turn the car on...watch in that little window and you should see a red light flashing. it will flash a certain number of times the stop for a second and then flash the same number of times again. count the number of flashes...at report back to this thread...go all the way to the bottom of the page where it says "QUICK REPLY" ....don't post "new topic"

then maybe we can help you. if this is too tough to understand then you probably shouldn't try fixing the problem anyways
