Jim* Posted February 22, 2013 Share Posted February 22, 2013 Okay so when starting my car from cold after leaving it overnight, it idles quite high, (which I presume is the choke?) and when I start to drive as soon as any boost pressure issue the car goes really jumpy and almost splutters and 'pops' which I'm guessing is the car just over fueling as when it warms up its fine? I have a full straight through and a relocated air filter A one have any ideas? Quote Link to post Share on other sites
pick1 Posted February 22, 2013 Share Posted February 22, 2013 Could it be a mid-fire when cold ? Quote Link to post Share on other sites
Jim* Posted February 22, 2013 Author Share Posted February 22, 2013 Do you mean miss-fire? Why would it be doing that? Quote Link to post Share on other sites
