i have a 95 ex.d16z6 vtec. it has been running wierd, when i drive it it pulses almost to have no fuel or something. the exhaust skips a little sometimes, and it has an inconsistent idle, when in idle it will start at about 800 and jump to 1500 then down and so on.i replaced the fuel filter, distributor, cleaned the idle controls,re-set the idle screw back, timing is right on, and i changed the idle a little so it doesnt vary as much. please help me with this problem i am a body man not a mechanic.any help is appreciated
