CEL w/ my Mazda 626
 

This is my wifes car, N/A, but the CEL has been coming on when I get on the highway, and when I'm cruising on the highway and I give it gas to pass someone, but then it will go back off once I'm just crusing again. It's the 4 cyl engine. I thought it might be something like the MAP sensor or something, but I dont even know where the jumper connector is on that car to check what CEL # it is. anyone?

Most likely your EGR valve. register on MX6.com if you haven't already, post in the 2nd gen forums, and tell em SixSick6 sent ya.

What year it is will help out alot. The oxygen sensors have a tendency of going bad. The jumper is in the drivers side fender well. Right beside the fuse box. In that area on most models...agian..the year would help out alot , and usually an Egr valve will only cause a really shitty idle...Not a check engine light. But its a good idea to clean that also.

www.mazda626.net is a great site for these.

totally forgot to post the yr, sorry, its a 94. Autozone can only check the CEL if it's a 96 or newer, douche bags >:(
