So, I have a Evo 9 Mr with a few mods I will go down the list here just to let you know what I have.

Extreme Motorsports TBE w/Race Pipe - Vibrant Muffler
Upper IC Pipe
AEM CAI
MBC
Custom Reflash

My issue is that, all of a sudden after about two months of having the mods the car started hitting fuel cut in 1st and 2nd gear. It cuts at about 4000rpms and just chokes it the rest of the way through the gear.

The car has been in the shop that did the work for about a week, they have tried putting my stock tune back on it, retuning, and then the tune they had made for my car and nothing. They have done a few other things, all in all he said that the car is fine. Runs great, has no issues driving normal just if you go to wind out first and second its cutting and they are really not sure why.

He has one last thing he is going to try to do today, and if that doesnt work then I have been told to put the stock parts back on the car. Which I may do and bring it to the dealer, or i may just trade it in and leave the tuning world. This is the second time that fuel cut has pissed me off to the point that i don't want to deal with these cars anymore and I am honestly looking to trade it in on something if they can't get it to work.

Unless anyone here can help me out or tell me what could possibly be wrong.

Please help, i do not want to lose this car!!! I love it and just want it to be right again!!!

If you have questions please ask and I will post answers asap.

 

how do your plugs look? may be time for a fresh set

 

I actually replaced them from the dealer myself before i brought the car in and gave it an oil change, then when i brought it to the shop he replaced them as well and nothing...

 

What plugs did you use? THe BRxES and BPRxES cant be used on a IX.

 

I got the NGK's from Mitsu directly... paid to much for them but no store in my area had them instock.

 

They were the Iridiums then?

 

Yeah

 

I was going to tell you to check your stock intake snorkel to make sure it wasnt clogging the airflow, but I see you have a conical filter.

What shop are you taking it to, by the way?

 

Extreme Motorsports in Odenton,MD. The owner Shawn is the one working on my car. He has been doing this for years which is why i trust him but I don't know if he will be able to fix this.

 

If they cant figure it out, I am sure ISP or AMS can. They are pretty close to you as well.

 

I heard about this shop called Agile Motorsports off of Rt.40 might go to them.

 

I just hope someone can, but i am not gonna go from shop to shop looking for a fix and paying all this money to each shop and they do nothing for me.

 

They are mostly a Subaru shop. Either your tune is bad, or you are having an ignition problem.

 

Where is AMS located? or ISP, i have never heard of ISP AMS site says they are in Illinois

 

ISP is in Beltsville, MD. I am tralking about Atlantic Motorsports AMS, not Auto Motor Sports in Illinois. AMS is in Gaithersburg.
