dont scratch where it doesnt itch?Another question for ya concerning the coil packs. I haven't ohmed mine out yet(truck runs good) but, do ya think it's a waste of money to replace 'em as long as I'm in there? I was reading the archived threads, and ordered the coil harness as a preventative measure. I have noticed, that coil prices are all over the place. Any idea on who makes an after market unit worth buying?
Not so strange... many modern engines run on what is known as a "Waste spark" system... reduces the ignition spark generation by 50%....There are two COP's (coil on plug) and two plug wires. The plug wires plug into each of the coils. Yes it is a strange set up indeed.
Thanks for the heads up on the resistor. Ignition will be next week. This week is upper control arms.If the Coil Packs ohm out ok and are in good physical condition, I would not change them out.. Save the $$$..
If the plug wires are in good physical condition, -providing- you do not find any oil in the spark plug wells, I would keep them as well..
A spark plug change, and CP harness wire may be all you need to do.
*If you decide to change out plug wires, make sure you keep / transfer over the (5k) resistor in the base of the short HT Lead: that resistor -is needed- to balance the Coil pack when firing..
OK.Now I understand. Pretty simple setup really.Only the short HT leads / plugs 2 & 4..
The wires for plugs 1 & 3 do not have a resistor installed in-line: the wire provides the resistance.
