Okay so when i down shift, my gauges and tach completly zeros out. when im still moving and its in gear! When that happends the radio turns off and the abs is on. anythoughts?

 

Have you tried running the code? I assume if it comes on it's for a reason. Is there any other lights on?

 

Have you been messing with any of the wiring in your dash?

Have you installed a new stereo recently, or alarm system, or modified ANYTHING before this began happening?

 

Just a thought but it seems that when you down shift you are putting the car under load, which means more amperage draw from your alternator. Test your alternator with a multimeter while running and see what volts you have. You should be between 13.8 and 14.4 (This is with no load on the car, IE. a/c, heater etc.)

 

I just posted the same thing on another thread, but check the green plug on your alternator/gen. for CORROSION. Clean it good.

 

Haha well glad someone thought the same thing
