Help!!! Gas Gauge NOR WORKING!!!!!!


Recommended Posts

My gas needle has a mind of its own now. I am experiencing inaccurate readings from my gas gauge. It is all over the place. Only time it is accurate is when it close to a full tank. After it gets around 3/4 of a tank, there is not telling what it will read. Has anyone seen this problem? If so, could you please give me a heads up? Thanks in advance. MODEL: 99 STS.

See my post #4 in the following thread, try using Techron as per the instructions at each fill up, or start using Tier 1 fuel with Techron added like Chevron. BUT be SURE to use the TECHRON correctly on a full tank

Thanks for your response. I really appreciate it. Do you know about how much the fuel tank cleaning and sensor replacement will cost?

As i noted try the Techron first, try it on a regular basic say every oil change and see what happens
