spirit-racing Posted January 28, 2014 Share Posted January 28, 2014 Thought id get some advice and opinions before I go ahead and rip my car aprt to diagnose the problem. As I boost/accelerate on full throttle when it reaches over 0.3bar it holds back, and completely changes tone. It goes from being smooth to being really rough and kinda feels like it's running on 3 cylinders. When it's light I'll make a few checks such as boost leak but I always though boost leek was a whistle, where as this issue is a complete lack of power and a really rough tone. All help greatly appreciated.Many thanks Ollie Quote Link to post Share on other sites
Eynonz Posted January 28, 2014 Share Posted January 28, 2014 You checked plugs? Quote Link to post Share on other sites
spirit-racing Posted January 28, 2014 Author Share Posted January 28, 2014 Not yet, I will do now actually. But I would have thought if it was plugs it would be having a irregular idle? Quote Link to post Share on other sites
Jay85 Posted January 28, 2014 Share Posted January 28, 2014 Mate check plugs, leads and dizzy cap and arm! If it idles fine but runs rough under load it's usually a sign that some ignition part is breaking down under load. Hope this helps 😉 Quote Link to post Share on other sites
spirit-racing Posted January 28, 2014 Author Share Posted January 28, 2014 Legend:-)!! I have ordered new plugs, will check the rest tomorrow in the sunlight :-) thank you pal , will keep y'all posted Quote Link to post Share on other sites
Turk Posted January 29, 2014 Share Posted January 29, 2014 One thing is to check if your plugs are gapped as high boost pressure stops plugs sparking when on boost. I dont know what the gap is supposed to be but im pretty sure its somewhere on the forum. Quote Link to post Share on other sites
spirit-racing Posted January 29, 2014 Author Share Posted January 29, 2014 Problem solved. New set of plugs, some fresh v power and putting all the original vacuum hosing on cured the issue Quote Link to post Share on other sites
