Kayleighhep82 Posted May 6, 2015 Share Posted May 6, 2015 Just had the car back from a tuning company lots of work done map timing belt clutch etc etc, driving up the motorway slip road give it some beans then the car started like bumping & seemed to be hunting slightly & idling around 2000rpm, also the Rev gauge needle is bouncing all over the shop not giving a true reading when I drive over 3000rpm, I've been told it may be a vac leak, what's the best way to find out if it is & any advice on what I can do to eliminate other things Quote Link to post Share on other sites
Sefton-EP91 Posted May 6, 2015 Share Posted May 6, 2015 Check ignition components mate! Plugs, leads, dizzy cap and rotor arm! Could be a vac leak aswell, check all vacuum lines ensuring connections are secure and no lines are split Hope this helps mate! Quote Link to post Share on other sites
Kayleighhep82 Posted May 6, 2015 Author Share Posted May 6, 2015 It had brand new dizzy cap & rotor arm 3 days ago, leads are updated silicone ones so not sure weather they would be a problem, plugs are pretty new too, I just took it out & it seems to be running fine now but over 6000rpm the needle starts jumping again :/ could it be an intermittent vac leak?Thanks aloot Quote Link to post Share on other sites
sosolid Posted May 10, 2015 Share Posted May 10, 2015 check your o2 sensor. on my glanza mine was messed up and when i floored it the car would hesitate and start shaking and just being weird. Unplug yours and sees if it sorts it out. Then you can know if its that. Quote Link to post Share on other sites
