[DeTomaso] more evidence I'm a not much of a mechanic...

Let's see, for a really fun party, come to Doug and Terri Braun's house; we're going to vote on what four items out of the following list we should do:
1) Discuss Panteras and other car-related subjects
2) Have a delicious Pot Luck Dinner
3) Enjoy refreshing beverages
4) Watch a couple of classic car movies
5) Work on Chris' car
If number five ended up one of the winners (due to a stuffed ballot box, no doubt), I'd most certainly be impeached! (Plus, I wouldn't have time to engage in #s one through four!!!)

If the problem is not the electronic ignition it's just gonna tell you all 8 wires are fine. Even if you pull a plug and ground it to see if it sparks or not, that is also no guarantee it is not faulty as I have known plugs that look good and are failing under compression.

If I did pull a plug, it would be no problem, since then the ground would be easy; the plug casing grounded with the wire still hooked up would simply let me see the spark plug sparking its little heart out...
