any reason for this shouldent the check engine light be on btw car is a 1987 turbo 2

 

Nope, it will not be on.

 

cool thanks runs like ****!

 

I'm no Expert but if your vehicle is an S4 you do not have a CEL. Mazda started useing CEL's in 88.5' and on..

You'll need to pull codes via the factory ECU. Refer to the FSM to further elaborate this procedure.

There is no Check Engine light on S4's.

 

Yea, no check engine light on S4's. I love it, I don't have to worry about what's not working right!!!!!!!!! She never complains!!!

 

lmao ok cool thanks for the help guys where can i buy the cheapest o2 sensor

 

A faulty o2 sensor does not cause your car run like an excretion. Spend your money else where on the car.

**** I don't even run an 02 sensor. I have never seen this car run better!

 

Meh, as pricey as gas is in Canada I don't see why you don't.

 

i would think that an o2 sensor would have alot to do with how the car runs also i dont like the smell of a full rich car
