Ok so i have encountered a few problems while working on my car... You guys have helped me though alot of problems in the past.

1st question -- My speedometer wont turn over and the needle wont budge from the bottom? Our these car run on a cable or elecrtic for the speedometer?

2nd question -- I have replaced my windsheild wiper bottle and new pump as well as all new lines. When i hit my switch in the car nothing happens. Any ideas?

3rd question -- When my car idols at a redlight/stop light it sometimes idols reall really rough like the rpms our droping and raising again until i start to move then its fine. There has also been times where i have been at a redlight and my car will idol so bad that it will cut out my battery light will turn on inside the dash? It will start back up again right after!

Thx for the help guys.. just let me no what you think!

1. broken or non-functioning speedo cable (not electronic on these cars)
2. wiper contacts or switch is fubar'd in the steering column. disassemble & clean, check all relevant grounds, measure voltage @ the pump, probably not getting 12V due to above
3. crank sensor could be dirty or wet, check connection @ dme, could be failing dme relay too.
