Wierd Idle When Warm

[polxc7]

Its not just the idle at warm but it seems like under load at 80klms before it kicks out of od it is really hesitating lke its cutting out. First start it when cold, it won't do it. No check engine on yet but really annoying. New plugs, fuel filter 10,000kms ago. Any suggestions.

Is the engine running clean?

Is the fuel pump running ok?

How many miles you have on it?

Pull the negative battery terminal for 5 minutes, and reconnect. It'll cause the ECU to reset.

 

Like Windows, if it's a ECU issue, problem will go away (it may idle a little rough until the engine warms up and the ECU re-learns though).
