Hey Gents (and ladies),

I have a question regarding my spark plug wires. I can't seem to find out what the resistance across each wire should be but here's what I have:

1- 7.41K

2- 9.81K

3- 11.21K

4- 5.22K

5- 8.26K

6- 10.15K


Does anybody know if this is normal for a 2003 V6 4.0?

Probably about right...Normal resistance is about 5K Ohms per foot, thus resistance readings will vary based on the individual cylinder wire length.

 

Thanks! Just wanted to make sure.

Now I just have to scratch my head and start from the beginning of my issues.

 

What type of issues are you having?

 

Lack of acceleration and power. I replaced the knock sensor which helped with the poor acceleration and timing issue, but the acceleration still isn't great but a little better than before.

Replaced the intake manifold gaskets since I was in there anyway b/c there was a slight vacuum leak. Ended up being a cracked/broken gasket.

Intake seems fine. Plug wires look okay. Plugs themselves "visually" look okay.

I'll be replacing the air filter today when I change the oil and leaky radiator.

My next guess is probably replacing the spark plugs just in case.

Any thoughts???

 

Being a 2003, I personally would replace the Plugs, Wires and Coil Pack. If not already done, I would also put a double dose of fuel system cleaner in a tank of fuel and then replace the fuel filter after running the tank of fuel down to almost empty. Also, by now being a 2003, I would have replaced my coolant 2 times after giving it a good flush. Power steering, Transmission, T-Case (if 4WD) and axle(s) would have new synthetic fluids in them.

However, this is me.
