Check the ( ETCS ). Electronic Throttle Control System ) fuse. Fuse should be located in the fuse box under the hood. Owners Manual would tell you exactly what fuse it is and location.

Thanks a lot will definitely will check. Could a bad spark plug cause this ?

There's not a fuse for that...don't see it in manual

Yes a fouled or missing spark plug can cause your problem.


When was last time you had a tune up ? And does your owners manual say anything about the wrench light what is causing it to come on ?


You may not have that fuse but take a look at the fuses some you can tell by just looking at it and see if it's blown.
