Hi guys
When my engine (g16a escudo) is running and you remove the oil cap the idle drops as if it is a about to stall.I can't find any obvious vacum leaks and engine otherwise runs well .Has anyone experanced a similar problem
cheers

I would imagine this engine runs a PCV valve, when the cap is removed the valve fully opens and sucks in more air than normal...
Hence the idle change... Or something like that....

Thanks
I have looked at a vitara with the g16b and it does not have the same problem

its due to the pcv valve or (positive crankcase ventilation).Don't worry it means its working correctly
