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.
