97 bon'eville fuel gauge issue

hi,

i see there is a tsb regarding an issue i have with my 97 but i cant find the actual tsb to read. the gas gauge says there is more gas that there really is. the the needle on gauge itself moves smoothly upon startup so i imagine the issue is with the float in the tank. i would like to confirm this before dropping the tank as it seems like a pain to do this. any info on this situation?

tia, peter

The TSB covers gauges that stay on full for longer than they should and then read high after they drive around 100 miles. The cure is to re-flash the PCM with the latest calibration code.

Easy way to test for that is to connect a good scan tool and see if its reading of the fuel level corresponds to the gauge level. IE if the scan tool reads the level at 50% and the gauge reads over a half tank the problem is likely the programming.

You cant get the TSB's free at this site, but with the numbers you may be able to find them somewhere else. Or just subscribe
