Afternoon everyone..
Short story long ... 2.0 bkd .. recently fitted a 1756 .. 4 bar map sensor and a couple of other bits.. headed off to the local tuners for a custom tune .. got a phone call a couple of hours in saying that no matter what he does to the fueling it massively over fuels virtually bang on 3800rpm.. even on stock fueling.. it rattles like marbles down the inlet. I've tried some tested second hand injectors .. and a second hand known good fuel pump and its exactly the same... bang on the money 3800rpm it's over fueling... any ideas would be appreciated.. it might have been an issue for a while as it never really needed revving that high..
