: Freelander 1.8 Engine cuts out decelerating and idling

I posted a similar thread on a well known Land rover website and got the really helpful reply of
I'd rather buy a regularly serviced vehicle with no mot than the opposite.

And I'd never buy a Freelander.

Apart from that, congratulations.
so I've returned back to .org and ventured out of the F/TF section again :)

We have a 2000 1.8l Freelander and it has recently started having an issue.
Basic background is she is pretty old and not brilliantly maintained -minimal servicing etc - but passed her MOT a couple of weeks back with no advisaries, so not too bad.

Last week however, she suddenly started cutting out when coming to a halt. Going down the gears and de-clutching to halt she just drops to 0 revs and dies. Happens only when the engine has warmed up. Generally starts straight away and can continue to drive, but it's a real problem as the missus has to get through traffic to get to and from work.

We have had the odd occurence of engine revs suddenly rising and dropping to near zero then just about recovering.

The plugs look fine, the leads look OK and anyway the way the cut out exhibits itself is not symptomatic of HT related issues. I've searched the web and aside from the bulletin, which I beilieve is outside my range I can find nothing specific to check.
I wondered about the IACV but havent had a chance to look at that yet. I guess possible ECU or leads to ECU issues are possible.

Any ideas?

Certainly worth checking the IACV, a friends MGF had almost identical symptoms and a new IACV sorted it out.

Worth checking also that the engine air inlet hose/ducting is properly fitted and has no splits as this will cause idling problems.

My sisters used to die going up hills and it was the crank position sensor .So theres another option :)

Had a quick look this morning just to see if there was anything obvious, but sadly no.

- no arcing on HT leads when running ( granted engine was cold so need recheck when hot)
- no obvious leaks showing and engine bay clean and tidy (for a car of it's age)
- wiring loom from bulletin 0007 is OK and the plugs are firmly connected (didn't have time to take apart and clean, but the seem well fitting)
follwed the basic checks from bulletin 008
- Check that all engine management vacuum pipes arebeen fitted correctly and not leaking.
- throttle cable is not kinked or has no sharp curves along its length.
- primary throttle lever mechanism has free travel and not fouling.
- that the correct air intake duct to throttle body clip is fitted. The correct clip is a spring band type. The throttle body looks in good shape,

Guess I need to have a closer look :(

Coolant temp sensor.

Does it stall when you roll to a stop and put the clutch in? What kind of MPG are you getting?

could be the idle control valve, or the sensor on the throttle body... same thing was happening to my white mgzr replica a year back, & we've seen it happening with a few customers cars too....

The key symptom is stalling on slowing down and coming to a halt and de-clutching when the engine is up to temperature.

I wondered about the IACV and will have a look at the weekend, but would have expected that to have similar issues when cold.

The trouble is all you repairers etc are Midlands based - you, Matt, Techspeed, Dave A. What we need is some sensibly prices expertise in the south

Certainly worth a shot for the £10 they cost.

my husband travels upto a 250 mile radius so for bigger jobs he'd be perfect, shame there isn't anyone in your area that could deal with the little issues for you... however i do hope you get it sorted...

And you'd be suprised with the idle control valve... my white mgzr replica only did it when warm, we changed it and it was fine and has been fine since... x

Decided to clean the IACV and check all the connectors before changing anything. That way I could remove one thing from the equation getting the engine hot while going out to buy a temp sensor. Took her for about an hours drive including motorway, normal urban, stationary traffic and most in between.

The idle was not perfect, but not a single stall or attempt at stall. If anything it held a bit high before dropping to normal. So either the IAVC was not seated properly and leaking air, there was an electrical connection not perfect, or there is a wire which is partially damamged and it shows up only under certain conditions. Or of course the IACV or Temp sensor are US and they are playijng with me today :lol:

I'll let SWMBO drive it for a few days and see what happens.
Thanks for the suggestions

Well her trip to work went without a stall so a good start so far. Tomorrow is the trip that normally causes the biggest problems so ....

Worked fine apparently - which is good news as I have no time to look at it now the
TF is playing up with the coolant venting.
Hopefully it was simply collective dirt on the plunger or elec connections

Typical :lol: why is it when 1 car plays up, the other one likes to come out in sympathy :dunno:
