Somewhere in the maintainance guide is Kevin Wood's excellent guide to battery/alternator checking .. might be worth doing that ??
Seems to me the poor running occurs under high current conditions .. could be a voltage problem that is upsetting the ECU
You could try switching headlights on/off and seeing if that affects the running
Clutching at straws I know .. but high load seems to be a common factor ??
I shall do that as soon as I can find my multi meter
a cursory check of the terminals suggests that they are in order; no fraying, vaguely warm to touch (engine running, lights and blower on).
No problems starting the car either, always first attempt, usually firing as soon as the key hits 3.
Car idles at 700rpm on start, then drops to 550 once warm, lights and blower do seem to make the idle worse. Emissions light is on constantly and flashes periodically.
Will re count codes tomorrow, eyes tired today, but seem to get the following:
0430, bank 2 precat. Probably got some plug electrode stuck in it.
0300, multiple random missfire. Not surprising if hunting around :-/
0304, missfire pot 4 :-/
0305, misfire pot 5 :-/
0306, misfire pot 6 Not surprised having destroyed previous plug. :-/
0110, air intake temp voltage hi/lo. Not sure on this one.1111, air intake valve 2 voltage hi/lo/open. Front multiram wasn't securely plugged in.
(I'd removed the ducting to move radiator back in order to swap the condenser over).
Not sure where the previous codes have gone, not showing with pedal trick. :-/
Rpms are read from dash.
