As per my previous posts i was having a problem with my car misfiring when coming onto boost only when i did it steadily. When i booted the car it was fine. The cars a C20LET nova
My fueling was up loads too and i kept getting code 38, even tho i had a new lampda sensor. If any one has a similar problem then check the throttle body gasgets 1st (top and bottom) mine were shot. This was after changing the necessary culprits like dizzy, leads, etc £££'s
The car boost like a dream now and runns a hell of alot smoother.
