Vauxhall Zafira erratic revs

Car: Vauxhall Zafira
Variant: comfort
Model Year: 2001
Categories: Running Rough, Starting & Power Loss
warning light with spanner comes on not all the time but when it does the revs seem to go up and down as so far as it seems it wants to cut out no loss of power at all no codes showing as well

Should have stored a code if light on . Check all vac / breather hoses for leaks .

As already suggested would be looking for fault code first.
