Saab 93 problems
Any Saab experts out there? A mate at work is having some bother with his.
Its a 1998 S, Saab 93, 2.2 twin turbo. He thinks it has the trionic 7 ignition system. Car has done approx 110K miles.
When cold it runs fine. He's noticed that when it is fully warmed up and he stops for a short while (eg 10 mins to go into a shop), when he sets
off again the car stutters when trying to accelerate thro 2nd and 3rd gear. He has also noticed it start stuttering on a long run even if he doesnt
stop but no where near as often.
Does anyone know what could cause this. He half suspects the ignition cartridge may be to blame but doesnt know enough about them to be sure (and they
are £180 to replace, a bit much if it doesnt fix the problem!).
Thanks in advance for your help.
Darren.

Ignition cartridge is certainly the prime suspect, but it might be worth putting a new set of plugs in first -- even that isn't a cheap fix on
modern cars.

Try http://www.saabscene.com - someone on there is certain to know exactly what's going on - beware though 'cos they're the biggest
bunch of winging gits I've ever encountered on the interweb! I eventualy gave up on them as I seemed to be in the minority in actualy liking my
Saab 
PS probably not ignition cartridge btw as they usualy either tend to work properly or they don't work at all on Saabs

The thing to watch when buying a replacement is the colour of the cassette this indicates the model type of the trionic system -- trionic 7 is black

If it's a 1998 it's certainly not a Saab 93. The last year of production for the 93 was 1960.
I suspect your mate has been fooled into buying a Saab 9-3.

Ooops, my mistake, im not a Saab expert - it is a 9-3.
Hes just checked and it is Trionic5. BT's link list the parts for them as well.
I trawled thro saabscene. It appears the ignition cassette jobby could be a suspect but it would be nice to here other peoples experiences as well.
One of his suspicions is that when car is running and warming up from cold it has air flow under bonnet. When stopped the air flow stops and
components under bonnet get soaked in the heat. Could this make a suspect ignition thingy go faulty until it cools back down?

2.2 - is it a diesel? if so I'm no use to you as I've only ever had petrol Saabs. Petrol turbo ones were comonest as a 2 litre.
The only way to know for sure if it's his DI cartridge is to try a different one and see if it cures it as there aren't realy any tests
you can do on them. Not a lot of help I know! espescialy as if it is the cartridge then it wont be long until it suddenly doesn't work at all,
they don't often give any warning of impending failure at all btw.
Whereabouts are you as there are quite a few very good independant Saab specialist garages dotted about (I would avoid main dealers if I were you) who
will be able to diagnose it properly for him

the heatsoak certainly sounds a plausible explanation, causing some component to degrade and affect the map, unless its one of the engine sensors
being affected in the same way?!

Coil packs generally are the weakest link on recent petrol cars, the fact that they are exposed to higher tempertures than old fashioned coils seems
to be the culprit.
Oh and the advice to change the plugs still holds as sometimes ht flashover at the connector end of the coil pack can be the culprit and this leaves a
conductive deposit on the plug insulator.
If its a a 1999 I am pretty sure it will have standard EOBD. EOBD diagnostics scanners can be bought very cheaply (16 to 40 pounds) and will read
all diagostic read the codes. Don't confuse these scanners with the Draper/Gunson type tools.
I just ordered a new top of the range one from thse guys http://stores.ebay.com/alpha-bid

Try DCA on 01635 860086 - Alan or Simon. They break, repair and generally what they don't know about SAABs ain't worth knowing. Lots of
2nd hand SAAB parts. Sounds like the ignition pack to me.Cheers, Pewe
