Dear Txgreasemonkey,

How do you send private emails? I have a 3.8 v6 2003 mustang. I had the camshaft synchronizer replaced with a Dorman part. It ran great for 2 weeks or so. Christmas day coming back from Cleveland Ga my car started missing under load and it may be called hiccuping. Finally a check engine light came on. It later was found to be cylinder 3. My brother replaced the spark plugs because of the tight area and it ran great except a very tiny miss up a hill not real bad maybe one or two. I took it to a friend's house and looked under the hood. Blue was coming out of one wire every 15 seconds or so. I changed the wires to Omnispark Oreilly's brand. Missed bad. I bought Motorcraft and it looked like a blue light show. Ran good at first for a few miles then started missing. I bought Autolite from Advance and it ran good for a little bit went haywire missing. Sometimes it would run on the other wires for 3 days with little miss or none. I went outside and did a soapy water solution twice at different times and the car idled down which I have heard that is because the wires are bad. The strange issue is it ran bad for 7 days or so and when I put the water on the wires and the coil it quit missing. No doubt conincidence. I only see some blue on two wires slightly on the Autolite wires. I have been told the coil could be bad and putting too much spark out and destroying wires. I have 118,000 miles on the 3.8 v6. I wondered if the camshaft synchronizer could have not been taken out right possibly top dead center or marked and put in wrong would it do this. The only thing is the problem started at cylinder 3 and it ran great when the plugs were changed with that little miss on a load. My brother checked for hairline cracks on the plugs. Thank you for your help and may God continually to bless you as you press toward the mark of the high calling of Christ,
Chris Reynolds.

Thoughts:

chriskrey, I would only install the same Motorcraft spark plugs that came in the car, ensuring they are gapped to specs. They were likely single-platinum plugs. Stay away from double-platinum plugs--they are much more prone to misfiring, especially if the gap is different from specs. Also, be sure to apply dielectric grease to the top electrode on each plug and to the spark plug wire connections. Coat the porcelain portion of each plug with a light coating of dielectric grease. All of this will help prevent the wires and plugs from discharging, except directly into the plug. This will help prevent misfires. Finally, be sure to strategically place wire separators.

Personally, I would use Motorcraft wires and wipe each one down with silicone spray. This will help prevent the secondary voltage from finding an alternative path to ground.

Hope this helps--keep me posted and God bless.

Thank you Txgreasemonkey. It does help a lot. I will go back to Motorcraft wires and the plugs were Motorcraft and I wll do exactly what you said. God bless you and if we don't meet on this side we will have all eternity together to praise our Lord and Saviour Jesus Christ

Amen.

After you apply the dielectric grease to the end of the spark plug wires going to the coil pack, ensure they are fully seated.

Thank you. I read your profile and I misunderstood the last statement I thought it said if you know you're going to heaven send me a private message then when I just read it again I saw it said if you don't know.

Thank you again very much for your help I love what you do and have done for our Lord.

Thank you for your kind words--I hope I have helped you at least a little bit. Keep me posted with the results.

You have helped me a whole lot. I really appreciate it. I will keep you posted and thank you for your concern wanting to make sure all goes well. Thank you for your prayers and I hope you have a blessed night

My thoghts:

Any possibility that the spark plug wire routing was disturbed?

Crossed wires and/or wires running next to a wire destined to fire next in the firing order. e.g. If firing order is 1 3 5 2 6 4 make sure wire 1 doesn't run closely in parallel to, or cross near wire 3.

KeepItSimpleStupid, Thank you for responding. They weren't but that is a good thought I had checked them and took them off one at a time. It was jerking real bad and we changed all the spark plugs with Motorcraft and it ran a lot better until I changed the wires and that is a good thought about keeping cylinder 3 away from 1 .

Sorry just getting back
