Surge when in overdrive, with rpm at say 3000, the surge will go from 200 up to 900 rpm for several seconds then drop back down. then do it again several seconds later. Only happens when engine is completely warmed up.does not always happen when driving but does quite often. new exhaust system was installed recently and the surge stopped for a couple of weeks, then returned again and has been doing it ever since.
