Ok i got a problem with my sr.Its pretty basic sr setup.First when the problem first started i would get on it and it would kinda feel like it would miss or hesitant for a secend.now its at the point where when i rev it,it hesitants for a couple seconds.and when im driving it and get on it ,it wouldent go past three grand and it also cuts off alot when i stop real fast dont know if thats got any thing to do with my problem.but iv done a fuel pressure test press was about 40 psi.changed out turbo cus mine had a lil shaft play and still doing same thing and i also changed the spark plugs.so at this point im lost so if anyone has any helpfull advice it would be greatfully appreciated.thanx

not reving past three grand is a common symptom of a maf sensor that is bad, dirty, or has faulty wiring. testing your maf sensor would be the next step in figuring out your problem

check for boost leaks. 40psi at idle is too much too, you want exactly 3 bar at idle with the vaccume line off.

I too was going to say clean the maf but I see that you have that covered.

check for vacuum leaks. if that's alright i say the next is try the fuel pump and make sure its working properly.
