got some codes and results of tests need input
well went to a buddys shop and did the injector tests. all buzzed good and loud. did the contribution test got p0284. ran a self diagnostic test and got p0476.
i know that the injector code comes back to #8 and that the other code is for the ebvp performance. i do have white smoke on first start of the day or ifr it has sat most of the day. i also have a constant knock that stays with the rpms the only time it quits is when i let off of the go pedal when im going done the road. i also dont hear it at first start til its been running for a few minutes. any help would be greatly appreciated. thanks guys
