I have had Bosch platinum 4 plugs for about 12,000 miles and about 2 weeks ago the jeep started running really rough and and missing horibally. It just happened all of a suddon, like in one day. I took the cap, rotor and plugs out and cleaned everything. I took the plugs to the wire brush and got them all cleaned up. I put it all back together and it started up perfectly and ran great like it had been previously. Then yesterday it did the same thing so I suspected the cap and rotor because it had been carboned a little and didn't think the plugs could have fouled already since I just cleaned them up 2 weeks ago. So I put a new cap and rotor in and it solved nothing. I pulled the plugs again and cleaned them and it fixed it again. i also noticed lately that in neutral, or ever since it started giving me thes problems, that the jeep has been reving at a constant 1200 rpm in neutral. i found an unplugged vacuum line and plugged it back in and it brought the idle back down. My question is, will the unplugged vacuum line and high idle cause the plugs to foul like they did?
TIA,
