Try using a gauge to measure fuel delivery pressure but this tool may only be available to the dealer or a big garage,best advice in a case like this is put car in dealers as you cant read the the ECU readings as the OBD II connector cable doesnt have manufacturers pin connections.Have a funny feeling this problem is a concoction of different faults,but try checking gauze filter on bottom of pump in the fuel tank or for porosity on the flexible connections that connect the plastic fuel lines to the unit on the tank .

distributor cap and rotor problem - there is your problem. If you do not put those suckers back in the same exact position, with the exact same markings, it will cause the car to fire the spark plugs at different times, causing miss fire and some times no firing at all.

Engine idle/running speeds sometimes excessive

You have a throttle problem (it gets stuck) take it to a mechanic and have it cleaned and greased up and that should solve your problem.
