Mr Slimm Posted May 10, 2010 Report Share Posted May 10, 2010 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. Link to comment Share on other sites More sharing options...
BodybyFisher Posted May 10, 2010 Report Share Posted May 10, 2010 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 http://caddyinfo.ipb...=1entry158235 Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...

Do you know about how much the fuel tank cleaning and sensor replacement will cost? Link to comment Share on other sites More sharing options...
BodybyFisher Posted May 10, 2010 Report Share Posted May 10, 2010 As i noted try the Techron first, try it on a regular basic say every oil change and see what happens Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...
