All,

I wish I would never have to make this post, but it is a last resort ordeal.

I put my evo back to stock, but I am getting no boost. I flashed the stock ROM back, and I am still having issues. Before anyone asks, I did do a boost leak test, and there are no boost leaks. I am lost to what the issue could be. I sometimes get a engine light, which only occurs at WOT.

My idle is high, at 2000 RPM. this only occurs however when the check engine light comes on. when the light is off, I am at normal idle.


See image below for codes. I really would appreciate some input here, I have tried everything. Including replacing the MAP and MAF sensor.

 

your wastegate could be stuck open thats about all that can keep you from getting any boost.
or turbo couldd be siezed

 

Was car running fine before? What codes?

 

Be helpful to know what modifications you removed as well.

 

Same thing happened to me a few months ago. My Mass Air Flow sensor failed. Got a new one, all is good.

 

thanks for the input guys, much appreciated. It turned out the actuator arm on my wastegate wasnt connected.

 

yuuuhhh! glad i could help! haha
