Hi,
Did a timing belt on this beast at the weekend, my god what a pain. The cuatomer had it back and all fine, today he phoned as he said, "its driving like a tractor" at 1500 to 2000 rpm. It accelerates well, and is very good at higher rev range. Starts well according to customer but sometimes it idles a bit rough. Before i go to see it tomorrow. Could incorrect engine tiing affect that one small rev range? I told him to fill up with fuel and put redex in and see if it improved and he got home ok. Am i being paranoid and this is just a coincidence? Any advice would be appreciated. Thanks James
