Misfire

[Y-SO-SERIOUS]

Hi All, 

Very new to Subaru’s and currently own a 96 STI import that was built at RCM about 10 years ago. it’s heavily modified running a GT35 etc... 

it was off the road for a while but is now back after being re commissioned properly. it is mapped to 2 bar but since being back on the road it has misfired under boost and struggled to make 1 bar. i replaced all plugs and coil packs (runs new age) after talking to Duncan at SSR but is potentially worse now and only makes 0.5 bar and can hear a misfire when not boosting. 

il add some photos which may be useful 

 

any help aprieciated and hopefully the above makes sense.

thanks 

chris

I've lately had similar issues that turned out to be lambda sensor and injectors, by also sounds like it *could* be a mass air flow
