Misfiring and check engine light
 

Had my version 5 sti impreza rebuilt and just been run in. Hasn't been remapped has mods like full exhaust system and induction and fuel pump. Today at 4500rpm it misifiried and check engine light came on. Now it won't go over 4500. What could the fault be?

Have you checked the fault codes?

No not yet gonna get it checked sunday

I believe this works on all classics so you can read your own

You should really be remapping with the mods you have done. Who did the rebuild if you don't mind me asking?

It's this page for code reading I posted ecu reset

Api did the rebuild. I've handed it into scoobyclinic for them to check it out.

Got it checked out by scoobyclinic and it was a maf sensor that was causing the issue. They've put a new one in plus given me 12 months warranty with it

has the car been mapped to suit the mods?

No it hasn't been mapped yet.

did the revs go over 4500?

Nope before they didn't but since having the new maf the cars been spot on
