Had that in a clio.... the temperature level was at zero even if it was warm, so I think the ecu sent too much petrol to the engine. It would shoot up then slowly come down....

Motorbike engine? The 1.8T pushes out 118kW.

Go learn something about cars before you post rubbish.

Please...thats more like a F1 car,

Here are my thoughts:

-Air Flow meter is faulty.
-Temp Sensor is faulty
-MAP (if applicable) if faulty.

Get the car scanned by a diagnostic machine, it will tell you exactly what the fault is.

Yep I will do that when I have time though.

I cleaned the MAF sensor on the throttle body and I found another wierd looking sensor on the air filter box. Maybe another air flow sensor perhaps?

@Sam . . . jou gat!

Yes, that is the AF meter.

 

[RazedInBlack]

Yes, that is the AF meter.

I see! Thanks Rickster.

High idle is most likely a vacuum leak somewhere. PCV is quite common.

I still have to have the breather pipe replaced so I'll see if that makes a difference. I'll be doing that over the weekend.
