Hi, just wondering if anyone has had a problem with there twinscroll running rough and bogging at low revs? Had a code for o2 sensor bank one so I changed that and the code has gone but now and then the car still does it, it’s fine past 3k revs it’s just low revs, cleaned the maf sensor but I don’t know what else is could be starting to annoy me as it doesn’t always do it.
any help will be appreciated
