Technical Another Abarth kangarooing problem, but different

[jarnom]

So here's one I couldn't find (and believe me I've looked everywhere)
My stilo abarth selespeed is having some weird kangarooing problems, it does it not only after start up but in every gear, and feels like the clutch in quickly engaged/disengaged while driving.
It pops up the engine control system failure on the dash and puts it in manual mode, and when you stop it usually stalls en gives a low oil warning, even though the oil level is fine.
Weird thing this that after I havent used it for a couple weeks it was driving perfectly normal and smooth for about 30km and then started again.
I have already cleaned the throttle body and all the main connections under the relay/fuse box but didnt help.
I dont have a fiatecuscan but we did hook it up to a regular bosch tester and it was saying it had problems with the throttle pedal position, throttle position sensor, and mixture problems bank 1 (already tried changing coil)
Will try again in a couple days while driving to see what it does, but does anyone have an idea or heard about this before?
Thanks.
