Unstable idle


Recommended Posts

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?

Thanks

Liam

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.

I don't have a wideband no! Thanks for the input though!
