what were the ones u said to use?! havnt got a new one yet the one i used was a spare 2nd hand one i had lying about. im gonna try changing the plugs from the cham 701s just to see if that makes any difference at all, doubtful but ive got a set of NGK iridium 9s kicking about so worth a try, what were the TPS's u said to buy again~?!
