The plug wires got here today and I replaced them. This car with 78,000 miles drives great and accelerates faster than this old man needs to be accelerating. It was a fantastic day for me.

I replaced the plugs and coil packs this morning in my 91 Coupe. My what a difference it made. This car was a bit sluggish compared to my 91 Convertible, I just thought is was due to the extra miles on the car,. The plugs that I removed were gapped at a minimum of 0.080" and I had a bit of a problem getting the wires off. I cleaned the ignition board with DEOXIT. All in, I was done in a couple of hours. I am waiting for the new plug wires to show up today, and if it isn't raining or too hot, I will change them out today.

So I placed an order for Sway Bar End Links [along with the Brake and Cruise switches] with Rock Auto last week and they arrived today. Just one side. I didn't pay attention to not getting two sets. So I placed another order for another Sway Bar End Link and yes scanned through other parts listings looking for other items to add without changing warehouses or adding to my freight cost.

The water here is a little deep here for me, but I gap my plugs at 0.055. I figure they will run a bit longer at optimal spark.

One thing I have wondered about is, does it take more energy to fire the two spark plugs in series or not? We have a waste spark system, so the circuit has two spark plug gaps to cross at essentially the same time. One is under compression and the other exhaust, so the voltages required are not equal, but the head scratcher is, are the two gaps added together, or not? The internet seems to have little agreement. If the wide gap requires higher voltage, which takes a bit of time to build up to ionize the gap, closing the gap, would have the tiny effect of advancing the spark timing??

The gap on one was 0.090", the others was around 0.080". should be 0.60".

That old spark plug looks downright nasty! It's always nice to have a car that goes faster than you want or can handle.
