The plugs are MotorCraft.And last night i went to leave to go to work got about 1 mile and the cel came on and sure thing misfire 2 and 3.But it is not always 2 and 3 somtimes it is 1 and 4.I made a point to call my tec and tell him that i was bringing it by this friday. I told him the problem and about the fans not running unless i turn the air or heat on.His first thought was a short or computer was bad.So he is going to run a test on it for $80.00 the test is for all things that go to the computer.Does anyone have any more thoughts.If i get it fixed i will find out what the problem is so i can post it here to pay back all the people that have helpped me in the last year.And for the new people that join in the future. thanks for the help.
