I have a 95 Dodge Neon Hi-Line SOHC it was running rough so I changed the spark plugs and put in some Champion copper plugs with a .45 gap. When I changed the plugs I found oil in the number 4 spark plug well so about 2 weeks later I replaced the o rings and gasket this helped the rough running a bit at first but it was still running rough so today I went out and changed the plugs again and this time I out in NGK G-Power platinum tip plugs with a .40 gap. The car started fine ran great while cold but once it heated up it started idling rough again but runs smooth and now I do not know why
. I checked the spark wires and they are good can anyone help? Is the gap too small perhaps and would this cause the problem?
Thanks
