My car is a 91 std. it has a fluctuating idle problem and smokes white, but only does it when its warm, wierd huh. when i pull the 2nd plug the idle problem goes away, but when i pull the third one the idle climbs and climbs until i rush to shut off the car. It drives ok but i think there is a loss of power. there is a lot of carbon/water coming from the exhaust. there was oil on the plugs top and bottom. I think my motors gone to hell and has a bad cylinder, but any advice would be cool. I would like to get some more life out of my engine that only has 115k before i do my swap.
