car still diseling run on prob

Plugs won't make it diesel?Inferior or improper plugs will make it diesel.Although I would check the timing first.Then I would make sure and run good fuel and it would not hurt to dump some additive in your fuel tank to help clean the carbon off your pistons and valves.Then if it still diesels put some cooler Champion plugs.My fathers Hemi was dieseling pretty bad I put in more timing and adjusted the idle and that took care of most of it.It still would diesel sometimes so I put a cooler plug in it and it has not dieseled since.That was two years ago.
