Why does my Optispark go bad every 30,000 miles or less?
Chances are that the venting system for the Opti is clogged or damaged. A properly maintained Opti lasts 100,000+ miles…yes, in real life. • Q: Why do my windows go up/down crooked? Or why do they grind? A: The plastic sliders in the track may have broken. They need replaced. There is an aftermarket version that is much better. It is a roller design and can be purchased at most parts stores under Dorman or Motormite pn: 74444. • Q: Why is my ABS light on (dash light)? A: Either a wheel sensor went bad or a connector is corroded. I’ve needed to clean the rear harness on 3 different cars. The sensors are very reliable. The harnesses and connectors are not. • Q: Why am I getting poor gas mileage on my stock motor? A: This could be caused by many things. Start with plugs and wires. Use Delco parts only. Then go over ALL of the vacuum lines. These cars are 13+ years old now. I’ve seen many brittle and cracked lines. Then check the A.I.R. pump system. Mine had a stuck solenoid on the A.I.R
