CO2 Query

One bit of clarity please.
My tickover is at about 6-700 RPM
Shall I set that correctly before adjusting the TPS, or adjust the TPS then set idle.
I know the engine shouldn't be running, but just need to know if the correct idle position should be set first.
Big thanks for setting this straight please.

i'd do the TPS then idle. can't see that it matters really.

A massive thank you guys
My TPS was reading .7 V
So, took it down to .36V, went from 145 per tank to fuel light on up to 170 to light on.
Tweaked it to .33V, now light on at 190
Re the .33V, I'll check my butterfly positions in better weather, but for now, I'm over the moon.
Thanks again

Glad it worked for you too.

Does any body know why the TPS goes out of adjustment? You would think that with the adjustment screws being 'sealed' with a dab of blue paint and the fact that Haynes says don't touch it that it should stay put. (Well I would anyway). I suppose it's a case of maintaining BMW's profits in doing a simple adjustment which if known about can be tackled by any half-decent home mechanic.

Cynic? Me? Never.

Anyway, glad you sorted it. Well worth the cost of a multimeter in petrol saving alone, never mind the log-term wear caused by rich running.

Take care

Local dealer had replaced hall sensor and had tried some other injectors. So I assume they fiddled with the throttle bodies; who knows
Anyway, what's the point in saving money, when tonight on the way home from work, the petrol station had a set of screwdrivers on offer, with a really natty flexible drive
Do I really need more screw drivers?
Mmmmm tools.....
