Hey guys new to this form here looking for some answers concerning my 2005 evo8/9.

So heres the problem i got a evo that was tuned by English racing it was running fine till it starting misfiring and running somewhat rich.. so i went ahead and got new plugs, cop system and new coils and a new front 02 sensor. I fixed the missfire and runs smooth at afr 15(idle) But as soo as i give it any gas afr hits bottom 10. And boggs and only hits 11psi. So is it bad injectors? I got new fic1100. But i cant get the car into a shop nor install the 1100s without tune. What should i do? Pull the stock injectors and maybe get them sent for a clean? Then install and see if it fixs it? Or install the 1100s and send my car back to English racing and get a new e85 tune?

 

Have it towed to ER and have them sort it out.

 

Well, you're in the the X forums and not the 8/9 but this will apply anyway. I'm guessing you have a boost leak. A leak after the turbo will make you lean under vacuum and rich under boost.

 

No boost leak. Did a boost leak test already. Thanks tho. And i though this was evo x form as in any evo xiii
