Re: intermediate "stalling" when accelerating
First thing I'd check would be ohming out the plug wires. If you check end-to-end, using a VOM, you should get resistance, but if you get the 'infinite' or 'overload' readings, the 'wires' have gaps that must be jumped in addition to the gap of the plug itself. It can cause intermittent misfire. Second would be the MAF cleanliness, third would be fuel delivered volume & pressure.
