Bypassed yesterday, but it looks like someone cut into the firewall before above the core... strange maybe it was done at the factory, the seams look somewhat professional anyways, since my scoob is RHD, the core is tailored as such and requires coming from another similar model or from Subaru direc...

Any guides for this?
I've read about people cutting the plenum box open to save $$$, is this an option?

I'd like to bypass the core for now, need my car for my job and a new core is
1-2 days out, don't trust one from a '94-'95 from the local salvage yard

Strange, the next day I go to take it to the import shop and... no CEL and no flashing "Manual" light
Go figure.
*closed*

Started car other day, "manual" light flashes 16 times then next day CEL stays on
it's still running but hope I didn't mess anything up
Code seems to be for #3 injector... where would this be looking at the engine from the front?
thanks
