so just asking if ud guys kno... one day i started my car and it was runing fine i left it on for a minute to run and get something and when i got back i looked at the guages and the RPM was going all the way up then down and the MPH all up then shaking back down battery up and down and everything blinking.. so i changed the battery and it happened agian the other day any suggestions?

 

1st you need to tell us what you have? The more info the better. Been tuning your car? Sound like a chip/computer prob or short.

 

I have had that in my 99 a few times, I just shut it off, restarted and it went away, never could figure it out, even worse if the batt had been desconnected for any length of time. I even had the dealer keep it for a few days and they could never reproduce it either.

 

oh sorry this isnt in my mustang its in an 02 town and country i was jw if u guys might kno anything
