Glowing spark plugs...
So i went to jumpstart my buddys jeep the other night. while we had the cable hooked up, i grabbed the throttle and revved it a couple of times. just small revs. i noticed out of the corner of my eye, that when i gave it just a quick tap on the throttle, i could see the porcelin part of the plugs glow and then dim. I was wondering if this is normal or not? still new to the rotary thing.

Classic sign your spark plug wires are bad...change them.

Ted's right, get some new wires.

So don`t worry this has not effect on what you know about rotaries since... Well Jeeps are not rotaries hahaha. I am sure if you Google or wiki "Glow Plugs" it will tell you if you can actually see them glowing from just looking at the engine. RETed and evileagle, i just replaced my wires about a month ago |
sorry, but i guess i shoud have stated that i am talking about the spark plugs on my 87 GXL N/A

What brand? Else, the spark plug itself is bad. Change one or the other to see if this fixes it. -Ted |

It could be your new spark plug wire is faulty?

i cant remember the brand off hand, but i did the plugs and the wires at the same time. im just not sure if its a bad thing or not to see the plugs glow a bit when i tap the throttle. when i noticed this, i had just gotten off the highway if that has anything to do with it

NGK. its all the parts store had in stock. when i got the car, it had nothing but leadng plugs, and all of the plug wires were on the wrong plugs. the old plugs were toast anyways

If the wires are made in China then they are probally broken already.

i am experiencing the same exact problem on my ride with rear rotor. when i rev up, the car sort of hesitates and the spark plugs glow. I will replace all wires and those two spark plugs tomorrow and let you know if it fixes the problem.
