Liam_D Posted May 23, 2013 Share Posted May 23, 2013 Hi guys just a quick question. My car seems to be suffering from rough idle. Only when I start the engine and it's still warm, never an issue when I start it from cold. Also it'll idle rough and then ill pull off and it'll drive fine then next time I stop and let it idle its fine again. Really annoying issue to be honest.Anyone had these problems? Any ideas? ThanksLiam Quote Link to post Share on other sites

mech5107 Posted May 24, 2013 Share Posted May 24, 2013 Do you have a wideband? Probably your lambda sensor has cooled and reports wrong. Mine does it and the rpms drop to about 650 and mixture leans to 16:1. Just a few blips to the gas pedal to raise temp and it's back again. That if your lambda is single wire. If 4wire, check/clean the idle valve. Quote Link to post Share on other sites
