Engine Revving and dropping rpm after using FES
Posted: 18 Apr 2010, 09:53
Hi,
I noticed this thing after using FES on my fiat punto '03.
the engine of my punto, in idle, stays a little bit around 2000rpm then fall down near 0rpm (like it's turning off) then come up to 2000 again, then 0 and so on....
I have to turn off the engine and then start it again to get back to normal.
anyone knows why?
I connected to this car only two times, first with elm the second with vag-com cable.
Both times I just checked some parameters and done some actuator tests.
nothing else.....
if no one know why, i could try to find out if it occours every time i just connect to the ecu or when i do something specific with fes.
edit:
If needed i can make a video...
