Courious if other Evo 8 owner have had the same issue, my car is in the shop for the second time, the service engine soon light has come on twice in the last week, the first time it was a random miss fire, this time they are not sure, they are going to keep my car so they can figue it out, has anyone else had this problem..

 

Yep get the random misfire all the time. What mods do you have to your car?

 

What causes this?

 

My service engine light turned on 3 weeks after I got my car. Due to the fact that I'm using a test pipe. Scarry thing is that I don't even know if things are going wrong cause its on all the time.

 

My car throws a miss fire code PO300 at least once a week. Its done that since the 3rd week I bought the car. The dealer cant figure out the problem with it, they have changed everything out on the car and it still does it. And I now have 11,000 miles on it. I guess it is a problem I have to deal with, because I am tired of my car being in the shop, and not getting fixed!

 

Mine is on.

It might have something to do with the fact that the rear O2 sensor is ziptied and dangling from the undercarriage but I'm not sure.

 

Read my new thread about the Backfire SES light!!!!!!!!!!!!!

 

Thanks guys, I have no mods yet. I had the guages installed by the dealer thats it. It has been in the shop since Saturday and they still have not solved the problem.... I am so glad I put off any mods till after the first of the year. So they have no excuses.

PS: They got me a rental and I am driving a ford focus, let me tell you how much I miss my car.. I hate it!!!!

 

Thanks wildman, I did read your post, hopefully you friend can get the answer we have been waiting for, soon.
