I have a 98 xj 4.0 ive been stuck with a misfire on the number 1 cyl. I have replaced plugs with copper (gapped to spec), wires, distributor (with a new cam sensor cap and rotor), injectors, fuel pump, 02 sensors, catalytic converter, checked manifold bolts, installed new valve springs, IAC, and a crank position sensor. Compression is low between 120 and 100 on all cyl. When i replaced valve spring (i used air to hold valves up) the exhaust valve on number six leaked a little. i could hear it at the tail pipe. So my question Is would a bad exhaust valve on number six effect number 1 and cause it to misfire also when air conditioning is on the misfire clears up. at least until the compressor cycles off and then when it cycles back on it clears up again. I only notice the misfire at idle. I no longer want to keep blasting parts at this thing can someone help me.
