My stalling problem

[Ash M400]

I can not remeber who said it, but it appears to be the air con.

Just found out today.

Is this an ECU update?

As to the smoke from the nearside tail pipe, could this be water falling on the exhaust from the Air con unit?

Kind regards

Ash.

I have stalling problems when the air is on, seems to drop the revs at idle to around 600rpm, just needs a bit more right foot!

[LaurenceFrost]

You can probably have the idle revs upped by a 100rpm or so.

here we go again, no idle compensation due to a lack of i/o in the MBE ECU, blae Noble for skimping.
Wont compensate for air/con, lights, temp or anything else.

I have found a solution to the stalling problem with the AC on!!!

Just practice your heel toe technique!

Mine stalls if the revs drop quickly. I just feather the revs down slowly with the side of my foot, and no problem.

It's not Noble specific, my Pork will hardly get off the line with the A/C on. Try manouvering in a busy car park with A/C and power steering on full lock. Anything below about 1800 RPM and it cuts out.

Ancilliaries such as those are heavy power drainers, that's why the fuel consumption takes a hit.

As has been said, the solution is the pedal on the right

it can be fixed though. My 3R done it from new and the dealer sorted it out.

Come to think about it I has just started doing it again !

I had the same, wound the throttle stop open a smidge.

Not being mechanically minded how does one do this?

Here's what I did... Follow the throttle cable to where it runs through a couple of 13mm (i think) nuts. With the engine running and everything on (front fans, aircon, full beam lights etc) loosen the locking nut, turn the other until you're happy with the idle and then lock it up. I've had no problems since.

The idle problem that some people may be experiencing is caused by a drop in air density, due to the hot conditions we're experiencing.

In addition to this, as your car's engine loosens up, the idle speed drops very slightly, which - in some cases - is enough for the engine to cut out when you close the throttle suddenly.

My own press M400 has suffered, too, but I now just apply a little heel and toe to compensate (as Dean mentioned). However, any Noble service centre should be able to raise a car's idle by around 50rpm, which can be done in a matter of minutes.

Thanks Simon,

As usual this is the kind of fast response we are all getting used to receiving.

I shall get the idle speed adjusted at service time.

I did the same idle trick by adjusting the cable on the M12 - worked a treat. I did get Moley to sort it out "properly" the next time it went in.
