One thing after another. Someday, I may be content
Since I've put the 8mm Taylor wires on, I've never been able to use the coil wire. The car runs great, as long as I leave the 7mm coil wire on. I put a new coil in, thinking maybe the old one was weak. Not the problem. With the 8mm wire, the car stumbles or has a miss or something.
I haven't been to worried about it, cause it does run good, but it'd be nice to know if there's any difference, with the bigger wires.
Just like to get a few ideas of what could be causing this.
Thanks.

 

I'm putting in a new coil sometime within a week and have not found an 8 mm replacement to go along with my borg warner wires... When I do get one, if I have the same problem, there may be something else at work here we haven't figured out.

 

I see guys using 8.8 mm and 8.5 mm, and figure it out.
These are only 8 mm. I put an MSD coil on, maybe not the greatest, but I thought it would be enough. There has to be something else.

 

Hmmm how are the RFI ratings on your taylor wires? I'm very very particular about that in my wires... if its as bad as I think it is, the 8 mm wire is inducing spark in the other wires and causing the misfiring... I still have a puny 7 mm wire that's running on 6 years now... I gotta get it replaced soon lol...

 

Taylor SAY'S, up to 10 times less resistance then OEM wires and eliminates RFI.
They're suppose to be top of line wires. I've never heard of anyone with problems because of them. That's why I'm thinking something else is wrong.
Right now, I'm running the 8mm Talyor plug wires and new 7mm OEM coil wire.
It works ok, just like to do it right.

 

Could be either a bad wire...or make sure it connected (clicked) good. Taylor's are good wires...but the coil wire is a tight fit.

Try some dielectric grease too

 

there's what they say and what really is... the only thing I can figure is the 8mm coil wire you're using must be generating EFI else it wouldn't misfire period.

The only other thing I can imagine and this is a long shot, but if the wires transfer A LOT of energy, we're taking peak coil output, then it is possible that the plugs themselves can't dissapate the heat created by the spark and they end up staying hot enough to misfire the instant the next air/fuel charge comes in...

Are you're plugs short or long? Stock, platiunum, copper, iridium? These factors may be what's making the 8mm not work. A 7 mm can only transfer so much energy, step up a mm and the potential energy transfer increases, so you need plugs to match the power output of the coil... Now the whole short vs long, if short, heat is harder to dissappate so tendency to stay hot and possibly misfire... long, has more area to disperse the heat, plug stays cooler... need more power to creat spark...

 

When I was planning on putting the headers on, I got a set of Busch platiunums, thinking or hoping I wouldn't need to change them for awhile.
A warning to anyone planning on going with Hookers, the plugs are near impossible to get at. You can't get a socket or wrench on some of them, from top or bottom. ( no kidding )
I'm hoping they aren't the problem, but may have to change them, as a last resort.

 

man o man ..all this fuss over wires....

My criteria for wires
1)Resistance
2)Durabilty/construction..(heat resistance & firmly connects to the terminals)
3)Price
4)looks


Since all of the aftermarket wires have less resistance from stock,Then I guess no.2 should be more of a concern..

just my 2 cents

BTW Accel coil/wires.GM cap and rotor,rebuilt distibutor(EVerything but the housing and gear was left),AC Delco plugs works great at 6500 on my car

Hey you can always go buy a Jacobs ignition system -- it makes all kinds of nonsense like this go away. No really it is quite the system the car runs like it's on steroids. I have new (well, one year old now) factory GM wires.

Of course I have yet to find a place to park all those pieces under my hood...

RP.

 

I was checking into Jacobs a couple years ago, before I had this car. It sounds like an impressive system.
It may be a winter mod. Unfortunately, I think my modding days are done, for now.

 

I couldn't get a 8 mm coil wire, so I bought a msd 8.5 mm coil wire kit... I still have a lot of excess wire left over after splicing so if we meet up again, you're welcome to it to see if it'll be a better wire option...

As for my car, I had no issue with the 8.5 mm coil wire, I cut it to same length as original.. think mabe could get away with less as less wire = less resistance after all..

 

Hey thanks for the offer, but I have tried the MSD 8.5 coil wire.
Like you said before, maybe it's the plugs, cause it doesn't seem anyone else is having this problem.

 

how do you route your wires?

daz are you thinking the 5-7 firing order issue why its misfiring?
