Hey guys Just wondering what could be causing a lag in acceleration between 3 and 3.5 thousand revs? It feels like I'm taking my foot on and off the throttle every second (kind of a very dampened kangarooing). It's amplified in 5th gear when on motorways etc...it's all fine below 3 thousand and above 3.5 I've run injector and valve cleaner through, only use higher octane petrol, new ht leads, and got some new iridium plugs still to fit. Personally I think it need new plugs.... What does everyone else think? Thanks, Rach.
