Mines doing it around 2800 again, isn`t that in the region where the FPR switched from resistor mode to full voltage? When my caps were bad it felt a lot worse, instant o2 trim would bottom out (sure I`ve seen it in the 40`s?) but o2 voltage was still pegged high.

I`ve got fuel filter, walboro and hotwire for fitting at the weekend, if my problem dissapears I`ll post back and that`ll narrow it down slightly. A 15 year old pump and relay may not be operating to there full potential..

A lot of people on the UK GTO forum seem to have cured it with just a fuel filter change?.
