Idle fluctuates

[Eman]

On my Bora 2000 model 2.0 litre 4 cylinder: while on idle I notice the idle hand dips suddenly. The engine idle does dip as well very little. I changed the spark plug leads and spark plugs and no change. What could be the problem.

Let me google that for you

i could be so many different things. run a scan on the ecu using VCDS (friend or workshop) and go from there. otherwise youll be at the mercy of the forum guessing game. It will cost you more time and money.
