(so i have ze curve neck with probinator ecu with no egr) this has happened since the swap which was quite some time ago but 1 out of 10 times or so when i start my car the check engine light isnt on which it should be cause i have no egr and it idle really badly until i rev it to about 3500 rpm the n the check engine light comes on and it idle fine again....... i was thinking of changing my stock gs o2 sensors which ones should I get? just the stock sensors again or would it be better to get the millenia ones or mx-6 ones?

my second question was is there a way to get rid of the check engine light even though there is no egr??...

third is that i have just installed a 2.5 exhaust with headers and when i start my car up from cold it pops quite a bit like a little back fire but once warmed up it goes away is there anything to fix this issue?

If you have the Probinator chip the CEL is not from the EGR. His ECU deletes the car from popping the light on from the EGR not being there.

Pull the code and see which on your car is throwing, I'm sure its not the EGR one

oh.... i always thought it was.... yeah ill check it thanks

so i pulled the codes and i have quite a few 3,5,15,16,17,23,24
so i guess the 15 17 23 24 means i need to replace my o2 sensors. im not sure if it is ok to have the rest of the error codes or not though...

Umm in my experience with mazdas, everything needs to be repaired b4 the problems get bigger.... yeah so repair it...

I belive the other codes have to do with angle sensors and that can screw up ur timing adjustments and cause whole lot of other problems.

I buy my 02 sensors from Rockauto or you can go to oxygensensors.com Buy the ones for your K8 and use Denso as they're the factory ones. Don't use Bosch. O2 sensors are important so don't cheap out.

Here is all your answers to your questions.
