: Hesitation on start up - 2006 STS

08-08-12, 07:47 PM
I think my battery my be going bad. When I try start my 06 STS, it hesitates like it is not getting enough power to start. My battery post are clean, but my reading are saying 14.3. What do you think?

14V is plenty. Could be something else. starter. wiring. could even be corrosion somewhere. or it could be the battery. just because it has voltage doesn't mean it has sufficient amperage. do you have access to another battery to try?

DdoubleE, Jimmy is correct -- your normal battery voltage range is 11.5 to 15.5 volts. If your battery is ever low, the BATTERY VOLTS display on your DIC will have LOW after the figure (see pages 3-77 & 3-80 of your owners manual for more information).

If you keep experiencing the hesitation, please let me know and I can investigate further for you at any point. My email is Katie_Lucille@gmexpert.com!

If you have a V8, have your intake manifold bolts checked.
