My 2004 Jazz has developed a serious, hope not terminal, problem.
When the engine is particularly hot (eg. yesterday after one hour in the freeway at 110-130 Kmh) and I switch it off (eg. yesterday I had to refill at a gas station), when I switch it back on the RPMs drop quickly, below 700, then the car accelerates by itself (as in an attempt to revive the engine...) then stalls. If I switch it on again, it does the same thing UNLESS I accelerate hard two or three times: then it gets back to normal (idling at about 700/800 rpm). If, at this point, I switch it off then back on again, it usually does not do that again.
It has been doing this for a few months, 6 or 7 times so far.
What can it be?
