6potmkII 0 Posted April 26, 2006 Report Share Posted April 26, 2006 hi guys the engines holding back/losing power at around 5000rpm, especialy in 1st gear. pulls nicely low down in the rev range but loses it all 5000+cars recently had new plugs, and coil pack, but not leads, could bad leads cause this? weak fuel pump?cheers Link to post Share on other sites
Russ_vr6 12 Posted April 26, 2006 Report Share Posted April 26, 2006 get a diagnostic done on it mate,its the easiest thing,could be any number of things from leads to air mass meter Link to post Share on other sites
6potmkII 0 Posted April 27, 2006 Author Report Share Posted April 27, 2006 had it done before when it was missfiring, and came up with afm, i now have a new one and it has stopped the miss fire but engine just holds back at high revs Link to post Share on other sites
bazz780 0 Posted April 27, 2006 Report Share Posted April 27, 2006 could well be the leads, i had a faulty lead (just one) and high speeds the cars acceleration was insulting, had a new set put in and voila.pop the hood at night, try listen out for an intermittent ticking sound or look out for a blue spark coming from near the spark plugs/leads and see if there are any clues Link to post Share on other sites
