My non-turbo 850 (after filling up--maybe coincidental, maybe not) doesn't like accelerating from an idle. It stalls out a quarter of the time or flutters a bit until reaching higher rpm the rest of the time. It doesn't feel like a vacuum leak (e.g., dancing around/idling rough). Is this consistent with a fuel system issue, e.g., pump or relay? I've also heard that the idle control valve or fuel pressure controller might be suspects. Finally, my ignition switch has been getting quite bad to the point that sometimes the key doesn't want to come out, and we always have to do the "giggle" to unlock the shifter. Not sure if the ignition switch could be a factor in stalling. Thanks in advance.
