Baxr6T Shakes At Idle And Interior Light Flickers

[stretcha]

My 2004 xr6t mk2, with 128,000k shakes a bit at idle, but its not a miss and a power balance test comes up clean. Its got new spark plugs in it and its not an intake manifold. Only happens when warmed up and also my interior light flickers. Battery is getting a bit old, but still pulls 388CCA. Car cranks and starts fine, and the alternator has 14.4-14.9v output, also its running rich, but my oxy sensor is putting out an up n down graph, which is good... any ideas why the three faults are present? Are they all related? Also there are no related codes stored in the pcm.

388cca is crap, battery is stuffed, check vct_err and vct_adv pids, error pid should be zeroish also 14.9v is slightly high, could be faulty regulator?

Cheers, I'll drop into work tomorrow and plug in the ids and have a look at the pids

Check pids. Replace battery if required.

most falcons seem to have a appetite for batteries.

some last for yonks, some lasts for months.

Any ideas why it might be running rich?

[bionicxr6t05]

Timing might have jumped

But remember, even if no cam error fault codes are present, it can still have skipped a tooth.

whats do you mean by a power balance test? how do you do this?

[bionicxr6t05]

Powerbalance is a function of ids that monitors ignition timing to determine correct cylinder operation in real time.
