When I change The gear the car is off

williamadam · Jun 30, 2019

I have 2.5dt range rover when I change the gear the car is off unless I remove my feet from the break and press the pedal and then change the gear from P to R, or from N to D.
Please, any advice or recommendation.

Don't understand your message, but the auto will normally move off when a gear is selected if you do not have your foot on the brake.

Thank for your replay, what I mean that I switch the car on and press on the break and then change the gear from P to R , then the car switch off.

Do you mean with engine running when you select a gear the engine stops? What is the idle speed?

yes, you are quite right again dear Wammers.

And the answer to what speed is the rev counter showing when the car is running but stationary in P?

If from a cold start the engine speed is 1100 RPM or so then drops to 750 RPM after a couple of minutes the idle control/cold start fuel is ok. If the engine is idling at 750 RPM and when you engage gear it stops, you have a problem with the injection pump quantity servo. You will need a replacement injection pump. You may be able to put this off for a time by increasing idle to 800 RPM or so with a Nanocom.

Thank you for replay, its 800 RPM idling, sorry what do mean a Nanocom?

Nanocom is a diagnostic unit from Black Box solutions. As your idle speed is already at 800 RPM the only solution is a refurbished injection pump.

Sounds like someone already adjusted the idle speed.

The book gives the idle speed as 750 +/- 50 rpm, I have one that idles at 750 and one that idles nearer 800rpm.
