had miss on #1, replaced bad ex valve, ground seat, 150 lbs comp now. still misses worse. replaced wires plugs cap rotor. still misses. replaced O2 sensors on passenger side, not drivers side. just discovered that one. still misses. took off upper intake hoping to find a bad spider. just a tiny bit of hose rubbing,no leaks, but the bottom of the lower intake is filthy, maybe from 151000 miles of life in minnesota. also my intake runners were black when i had the head off. both heads were black. i'm assuming the pcm was trying to take care of a lean condition when the o2 sensors were bad.like i previously posted, my daughter was driving it and it just lost #1. so now i'm down to the coil. how do i test it with a ohm meter? and what are the #s i'm looking for. Will a coil cause a miss? Please help me before i go get the "Captian" out of the cupboard!!! any advice is totally appreciated..Thanx
