I need a little code help. My car a 2001 boxster 5 spd is not idling smoothly the lights and A/C fluctuate with the engine rpm. The voltage according to the durametric reader bounces between 11.8 and 13 ish with the engine rpm and the battery light stays on. I am also getting the code 9133 61 term low engine running. Any ideas or suggestions for further diagnostics.

Thanks

Tarry

How old is your battery? 4 years or more and it is likely the problem.

Have it load tested and also the specific gravity of each cell tested.
