Hi Guys,
Well, I had the throttle body off yesterday which was a quick job and the following found.
1. Throttle cable 10mm out of adjustment
2. On removal of the throttle body, copious oil was present, very thin and brown in colour. There is a little reservoir moulded into the intake manifold approx 12mm x 12mm which was full of the gunk, and it was present all around the mounting flange too.
3. Cleaned all that off and had a look inside the intake manifold. About 1 tablespoon of the same dirty oil was sitting inside That's not right I'm sure. With a lint free cloth, I mop'd this up as best I could as it is a little restrictive.
4. Cleaned the throttle body and inspected the 'P' shaped gasket for splits but it seems Ok, but I have one on order as it is a little flat and hard.
5. All together now and took it for a 20 mile run last night, a/c on, and guess what, NO SPLUTTERING (New plugs not fitted yet)
Before I get too enthusiastic, I'll run it for a few days too see how it performs and replace the throttle body to intake gasket when it arrives, as I guess seapage is ocurring.
I'll take some pictures (2nd time around) and send them to Finn (hope you do not mind) so that he can post them. I'll add notes to indicate the findings 1st time round.
It'll be interesting to see if the oil has re appeared in a day when I change the 'P' rubber/gasket.
Anyone else found this on their car????

They do get very guncked up, there always seems to be a little oil that gets down the delivery pipe into the throttle body, and a damn good clean is an excellent idea!
My carb cleaner arrived today and I'll do the same and report back!
Please do fit the NGK plugs though Phil

Throttle body 'P' rubber gasket fitted, new NGK 7ES-11 plugs fitted (they perform great guys, thanks) and had a chat with a Saab engineer.
His conclusion is that the solenoid in the throttle body is on the way out as the splutter at idle is intermittent, and not caused by the a/c clutch. Admitted, the engine revs will fall when the clutch cuts in, but would not cause the surges that I have... 3 or 4 times in 15 seconds, he says.
I will consider what to do next, but now the engine has sprung an oil leak. The timing chain tensioner was replaced yesterday, where oil was seaping, and today, still oil on the drive.
It's back in the garage now where the engine is going to be removed for a complete re seal.....
What a week:evil:
Why are Saabs so complicated? Are their aircraft prone to such failures!!!!! No wonder we do not see many flying today!!!
I'll let you know the damage later in the week:x

Good luck Phil, lets hope its light on the pocket.
Sounds painful Phil
Now that I have got up from the floor, I'll give you the details of the garage visit:x
1. Remove Engine £500
2. Additional reseal labour £300
3. Balance chain kit £175
4. Timing chain kit £175
5. Head skim + crank test £75
6. Head/Engine reseal kit £105
7. New oil & filter Free Ha Ha:roll:
All plus VAT
Mind you, the engine is as quiet as a mouse, but at great expense and no sign of the spluttering at idle. Mind you I have not been on a run yet!
All this work was done by my local garage who specialise in saab & volvo, not a dealer.
Time for a large drink I think, that's if I can find some loose change in the car :evil: :evil: :evil:

Finally got to the bottom of this problem.
The throttle body finally died on the M20 and have now had a new one fitted. As I know my local garage well, the full cost of this will be met by a warranty company which came with the car when bought a few months ago.
Little compensation considering the amount I have spent
Total cost this time £580, and a free service next time.
Thanks to you all for your input.

I'm glad its sorted, it takes a while to feel confident in the car again though
Sure does Chris. I hope I have a few year trouble free motoring now.
BTW. The new throttle body only has 1 PCV inlet from the valve itself (not like the old one which had 2) It must be a revised design
It'll be interesting to see how it performs.
Thanks again
