Hi,

What is the spark plug wire resistance for a 1999 Ford Taurus SE?

Thanks,
Robert

 

There really is not a particular spec..
A general number we used was , 10,000 ohms/ft.
Can we ask if there is a particular problem that arose bringing up this question ?

 

Information in my Ford manuals states up to 5000 ohms per foot is acceptable.

 

I was looking for the resistance as one thing to check that might explain why I am getting no-code misfires.

 

There is a misfire counter function in the vehicle's computer.
It requires a capable scan tool to access this info.
If it is only one particular cyl or several cyls, will depend on where you go.
Without that info you are shooting in the dark.

If someone was careless when removing spark plug wires , you could be looking in the right place.

A fuel problem can also produce the symptoms you describe

 

Hanky,
I am looking at getting the OBDLink MX+, so let me know if you have any input on scan tools for use with phone/tablet/PC. The one thing I hadn't been able to confirm is if my vehicle's computer has a misfire counter, but you say it does so now I know.
In parallel, I was going down the spark plug wire road because I have a multimeter and can do some checking. I already made sure that none of the wires are loose.
I recently had the transmission replaced at the dealer. The misfiring wasn't happening before then and has been happening ever since then. It took two transmission swaps before that part was OK, so I'm thinking that in all the banging around that something else got messed up. Or maybe it's a coincidence.
I am about ready to purchase a scan tool and will post the misfire count(s) when I have them.

 

A suggestion, make sure the scan tool you might purchase has the capability to access that info in your vehicle..

Not all scan tools can do that. Hope you have some idea what a good scan tool can cost.

 

The manufacturer of the MX+ assures me that it will read Mode 6 data. Their concern was that my Taurus might not provide Mode 6 data.

My AutoXray CodeScout AXR1500 doesn't read Mode 6 data, but it did show that my Taurus does pass the emissions readiness tests, including misfires, and is not registering any codes. So, I will get a scan tool that does read Mode 6 data, and it should also help me get to the bottom of the 420 codes that my 1998 Ford Ranger is registering. Maybe it needs new O2 sensors, or maybe something else, but that's for another forum.

 

I now have some Mode 6 data but this is drifting off topic so I will start a new thread.

 

Sorry to say that data you posted doesn't look like any mode 6 data I have seen.
It is all in hex decimal form and useless..

What was posted is what the scan tool is supposed to spell out. What ever you are using is not what we need.. You need a real scan tool with the capability to decipher that info.
