Yesterday at the Autocross I had a plug wire come off. I think it was the forward bottom which would be a trailing???

heard a funking pop/crack sound from under the hood. Looked in there and could see the huge spark jumping from the plug end to the rotor housing. Made a good decision to shut it off before putting it back on. Looked like that would hurt.

Must have happened a bit earlier as the car became harder to start for a couple runs. after I plugged it back in the car ran great again.

Bottom line ( crappy dealer maintenance tech).

Oh and the car did exceptionally well against a Saleen Mustang an M3 and a 993. only cars faster were on race tires. The stock Potenzas are just about gone now.

 

Lower plugs are Leading and top plugs are Trailing. It is very easy to remember that way.

time for some new wires.

 

Time to do the maintenance MYSELF. These wires original equipment, only 17K miles on the car. new plugs were installed recently while the car went in for the engine re-call thing.

Car seems fine. Wife always comments on how well the engine runs after a day of autocross..

 

yeah, I needed new plugs a few months ago and there's no way I was going to let some "tech" do it.
Joe: make sure you check those plugs every 25K miles.

If you're in the market for wires down the road, I recommend the RB wires.

 

Shameless pic
look at my noob buddies eyes.

 

Jedi54, Is the DIY on how to change the spark plugs the same on the AT?
Thanks,
-Gil

 

yes,

or take one off and put the new one on...

beers

 

btw,

joe the lower front plug wire becoming dislodged is somewhat common..


food for thought..

So now you have to qualify that remark with why would it be common for this particular wire to come loose?

 

"Somewhat common" So it might be only a had few. But lets see what swoope says.

 

dont really know.. it was just something the master tech mentioned...

mine did it with stock wires.. and the spare motor i bought had arching on the plug...

was under the car yesterday to check.. was tight as a clam. but racing beat wires now...

beers

 

so glad that sig is back..

party on bitch..

beers

 

I think the RB will help with the falling off since they're such a tight fit to get on. (seemed much tighter the stock) Swoope, yours fit tight as well? (Crap! just set myself up on that one...)

 

yep dom, it is, if u want u can go to my sad and retarded thread on the diy section

 

Well put it back on. There.......problem solved. No charge. ;-)

 

Those RB plug wires are nice looking - wonder if they come in Yellow ...

 

Far as I know......only red......I wanted blue!
Check the website, but RB stuff is almost always red.

 

Yeah me too I want Winning Blue

 

Don't forget Mazdatrix

 

plug connectors can get loose after pulling them off a few times. You can use pliers to crunch the connector closer together. You'll have a really tight fit that isn't going to fall off afterwards.

 

True. And as common... I've always read the 90% of the time it's after they took it to the dealer for repairs.

 

Good tip! mysql101
