well idk if this is a serious problem or what not, but ever since i got my IX from the dealer its been acting weird. Everytime i drive past 4000 rpm in any gear my car starts to get loud and starts jumping and black smoke comes out my muffler.

It doesnt happen always but happened a few times today and im getting annoyed

 

take it back to dealer and ask wtf

 

i plan on doing that this weekend, it still has dealership warranty so i hope they fix it

 

hmmmm....... I had the same thing happen on my gti, I know it's not an evo but I was running extremely rich and it happen to be the front 02 sensor and the maf was was apparently trash. just a thought doubt it's the problem though

 

i thought it might be because of the front o2 sensor but wasnt really sure. whatever it is im taking it back to the dealer and having them fix it while its still on their warranty

 

...Uhhhh........................Exactly.
