My cat got an in accurate fuel gauge, the pointer keep moving during ride and going up and down . Do you guy have such issue ? And can I use the trip computer to replace the fuel gauge ?

 

This is somewhat common. Get a new FACTORY unit. I originally replaced mine with the Uro part from FCP and it was inaccurate after a half tank. The OEM one is spot on. Don't waste your time to save $50, get the real one. FCP took mine back and gave me full credit for it with no questions asked. I purchased the OEM one from them for roughly $100.
