engine cutting out

[royzels]

Hello to you all again.....When I am driving, on coming to a junction the engine revs fall to low, and the engine cuts out, which is rather un-nerving..Has anybody any idea as to what causes this and what is the way to cure it...My car is a 1995 LS400 mark3............... Thank you all again...... Roy.

Hi

This is a common occuring problem on the Mark 3  - To fix you need to clean the throttle body - hope this helps

As a temporary fix, if you leave the aircon on it might not stall - but it will almost certainly be the throttle body that needs cleaning. There is a YouTube clip on how to do this if you fancy doing it yourself:-

Could it be the Maf sensor?

if it's like a Merc you can unplug it and it'll run albeit a bit rough and without full power to get you home.

Roy hi,  The throttle body cleaning needs to be done from time to time BUT I can assure you it is not the fix for this common problem

none known to my knowledge, my indy has tried absolutely every which way and can't solve this irritant.

Roy this is a very good forum - I am having some audio problems and a member here has offered to send me a replacement CD player if I need it - The forum at its best

And I should add, this is a way of testing the MAF as the motor might run roughly but it won't stall. 

I gather it can be a fuel pump or fuel pump relay breaking down but I think this is when the pump is hot.

I'd be surprised if it's the throttle body.

Worth checking all air hoses and associated clips.

Thank you Roy.
