GT3 Mk2 Lumpy Idle? Is this right? Only a little

[Jibberingloon]

Well i have bought myself a MK2 GT3.

But the one thing i noticed was on idle the Revs hunt a little bit, and not as smooth as some cars.

Is this the case with all GT3's??????? I suppose it is a race bred GT1 engine!

I have got the OPC looking at it before i collect it, so if there is a problem they will sort it.

Cheers

Normal .

In fact ... It's one of the things about this engine.

[PolarExpress]

At idle, the revs should not hunt and it should be completely stable.

[Jibberingloon]

Its only minor.....

Just a small amount, will see what the OPC says.

Mine doesn't hunt either.

[christer]

I would describe mine as not hunting at all, but rather its a slightly lumpy idle compared to say a standard 996.....

[Jibberingloon]

I would also say its more lumpy now....

Not hunting...

Stightly Lumpy.

MAF sensor might be contaminated? This makes the car lumpy at idle and slightly jerky sometimes at low revs/speeds.

In the grand scale of things not a problem to fix (£350 for a MAF) and dont let the OPC charge you anything for fitting - it takes about 2 mins to change a MAF - though they will probably charge for half an hours labour !

I've got a MKII and mine is lumpy too at idle - It's characteristic of these engines

[gordonc]

Comp called Dingbro up in Scotland bosch part no, as BOSCH make it so you should get from any motor factors for around £85.00 +vat huge saving amd 2 screws to change !!!

[ChrisW.]

Good advice on the Bosch MAF sensor, but both of mine have been lumpy at tickover --- a kind of high lift cam thoroughbread tickover !

[DiscoColin]

Another vote for slightly lumpy at idle. Just enough to let you know that it is not just a 911.

Can we elaborate on the Lumpy

Is it stickin' at the 750 mark but having the odd missing feel to it?

[Jibberingloon]

thats about right....

Idles with the odd little dip and rise of 100-150 rpm.

So not really a problem, just want to be safer rather than sorry....

Mind you i have a 12 Month OPC Warrenty so all good

[996TT_STEVO]

Can I confirm this is the case with most like Jibber has mentioned

[Merritt]

If the car has had a clutch change in the past - the previous owner may have put a single mass flywheel on. I did this to my MkII when I changed the clutch and it definitely makes the idle less stable than standard MkIIs.

Sounds like a nice spec.
