Stalling issues

**Discotracks** · 29th March 2017, 02:09 PM

My 93 D1 V8 is stalling at times. It only seems to happen when the engine is at temperature and coming to a stop, and on inclines at low revs.
When it stalls the oil and battery lights come on, but it starts back up again with no problems. Any ideas on a fix and what it could be?

I've tried cleaning the carby out and checked all the air hoses for leaks, which seem fine.
I'm sure theres a thread on here already about it, but tried and couldn't find it.

Thanks in advance.

On top of the engine air intake is a small recess with a 3/16 allen key screw inside of it. This is the base idle screw. Unscrew this screw a couple of turns and see how the idle settles down. The idling speed is normally controlled by the stepper motor mounted to the rear of the engine next to the brake booster, and gets slow in its old age. The base idle should be set at around 500 rpm with the stepper hose plugged, but just adjusting it up a bit via the allen screw may be all you need.

Oh and you don't have a carby, it's EFI.

You're right, eeek! - I'm new to the mechanics of cars. It was the Throttle bit I cleaned out. Thanks for the reply, I'll give that a try.
Right now on start up it idles at around 500 rpm.

500 is too low, i'd start by adjusting that up to at least 750.
