Hello, I have a 2003, 1.2l, 8v MK2 Punto. The problem with it is that when warm, and while revving past 1500rpm, it sometimes stays revved up even after I take my foot off the accelerator pedal.
For example, I was parked yesterday, with the engine idling at abou 800rpm. I then pinched the accelerator pedal with my foot, and suddenly the rpm went up to 3000rpm and stayed there. Turned off the engine, started it up again and it didn't do it again.
The problem is that this thing is intermitent, and it only does it with the engine warm.
I changed the throttle body with a new one, I changed the MAP sensor, the crankcase breather hose, airfilter and sparkplugs... but it still does it.
What else could be the cause for this?
