its a 94 wrx wagon. Its not boosting right and after giving it some foot, got to a junction and the car died out. Got know codes showing up, could it be the icv or maf sensor? cleaned the maf, the code did show up for the maf, but now got know code but still the problem.

 

sounds like a coil pack??

 

Do you have an after market dump valve?

 

plugs or o2 sensor thats what mine would do had to keep revving it to keep it from stalling,very embarrasing

 

After market dump valve could be the cause of it stalling.

 

mine had standard recirc valve,and that was replaced along with a lot (of expensive) engine sensors no codes on ecu or on garage machine so it was trial and error,not cheap either

 

no had a service recently, new plugs etc i think its the new dumpvalve, its actually been back to bailey to be fixed. or a leak in the intercooler pipe work etc and the lack of boost.
