William Thanks! I have only owned the PA for just about 45 days now. It was in need of some clean up but was in good shape with recent work. I got to Power washing, under hood detailing etc which is all done now. Yesterday, I had the interior all shampooed with a detailer'* steam evacuator, including seats & mats etc. Even smells good in there! Overall this car is in very good condition no rust and is clean under vehicle (was Arizona originally) It is getting better every day with all the mechanical I have done in the last weeks, front brakes,water pump,thermostat,hoses,tires,filters (cabin) etc. The 4 wheel alignment made this car way better in cornering! I was also happy previous owner had looked after this car and had just replaced the intake manifold and gaskets etc with updated units.
I have to say the new Iridium spark plugs & new wires make this ignition better than before! Can feel a smother throttle response & idle now. Probably easier starting now too! I found this link from NGK about Iridium Plugs/ Benefits:

I am liking my Soft Ride Air Suspension. I am now almsot ready for a long highway boogie!

In the next week or two the rear brakes are going to be fully renewed even though there is 40 % there, I want new rotors & pads in there!
Thanks for all your help!

Art, I just replaced the plugs and wires in my 98 PA. I went with the Autolite 7mm Wires primarily because in the past when I have upsized the plug wires I ran into problems with the looms. The 3800 has nice looms for running the 7mm wires. If you go with the larger wires they will not fit in any of the looms. I used the NGK iridium plugs. It seems to run real nice now. Time will tell if the iridium plugs are worth the money. I have never had any complaints wth the $2 plugs I had been buying. They always looked pretty good after 60-70k miles. I love my SSEi when I want to drive hard but, you got to love the smooth ride of the PA out on the open road!
