all 5me engines are leaded.

1st. why are you saying its running lean? - have you had an emissions test?

2nd. part of the emissions gear is an air pump, it pumps air into the exhaust manifold, removing this would make it seem like the engine is running richer.- but it has no actual effect on the air/fuel ratio at the time of combustion.

1st. It is running rich and i know this because it is blowing large quantities of smoke on idle, which (idle) is very very rough and sounds like it has been choked of air flow.

2nd. the tailing/s bolt that were on the on exhaust manifold were snapped by the exhaust shop. They only blocked 1 or 2 as far as i could tell and the others were left unbroken.

No emmission gear (vaccum hoses / sensors) have been taken off the engine and therfore could be creating a false impression or diagnosis to the ECU (<- if that even handles emmissions gear.)

(and to add to insult - it has started backfiring on cold starts...)
