Been asking a ton of questions and I really appreciate the comments. Rented my buds garage bay today. Changed the plugs probably fist time in 15 years. Electrodes were almost missing. Every plug wire pulled apart. Fixed the speedometer cable. Used the 100" with no cruise stuff. Perfect length. May read 10 mph fast. The basic tune up was what it needed. Laid 50 footer today car is totally different now!
