So I created this thread a while back and have been dealing with having a bit of a broken car for a while now.


My car seemingly works perfectly fine when you drive it calmly. However it suffers a weird stuttering, when your in say 3rd or 4th and floor it.
As the car tries to get going it stutters.

However if you feed the power in gently then it will go as fast as its meant too.

I did also make this thread with some ODB2 error codes I'm getting, which makes me think the two are related.


On advice in the previous thread I have change all the spark plugs and all the ignition coil. No luck.....
The only thing I've changed recently is the battery after mine died, I however was given one from a friend who had one on the shelf, tbh I never checked thoroughly if it was sufficient, although it works pretty perfectly at running everything else. (and he said it was the right type)
Do spark plug use battery power or alternator power under load?
I have checked the air filter, which is fine. The only other things I can seem to find Googling is that it could be waste gate related.

So I'm asking for any advice or ideas on what it could be, related to these things. Maybe battery, ecu, wiring loom (which looks fine on inspection)

Getting a little frustrated and I'll probably take it to a garage soon, as it's beginning to get annoying not being able to drive it like I stole it.

Thanks.

I've had similar issues: first time the issue was a broken intake tube. Second time it was an ignition coil even though I swore I'd ruled it out. It ultimately took another Saab owner who had known good coils that I could swap in.

Plugs NGK PFR6T or D-10G.. Are they oe coils..any codes..
Yep the correct plugs. They are original coils from another car off ebay, only thing could be that they are also bad, but I doubt it and frankly I'm not gona spend another £100 odd quid testing that theory, just yet.

It's was throwing these codes at one point but I cleared them to see if they would come back... I will check again which have and report back...

The most worrying being the general electrical failure and EEPROM (whatever that is)

If you have a second set of coils, swap out one at a time & go for a short drive after each one. That's how I figured out that both my old set AND my spare set had one bad coil.

They go bad frequently so I would not at all be surprised if the other set you got off another Saab had a bad one.

Can't harm I guess. I'll give it a go.

I’m having exact same issue on a 2010 9-3 biopower 2.0T.
missing/Stuttering when try to accelerate fast from cruising and sometimes when driving slow to try and go fast.
Everything feels like the missing is spark/electrical or fuel supply but if I change down manually and go high revs it performs fine.
Going to change plugs, then coil packs and see how that goes But it’s not a huge issue when driving normally so in no rush.
would be great to hear your progress. Cheers

I've been dealing with this lately. Another thing I found was a broken PCV hose (hard plastic emissions tubing). I changed that and it still misses. I have seen any other missing or broken tubing.

Good luck on your stuttering Saab. If you figure it out, please let us know so I can fix mine and sell it.

I recently had a MAF sensor do the same thing. It would stutter on full acceleration and had just changed both plugs with ngk pfr6t which I tried at both 1.0 gap and .8 gap. Then 4 new Saab branded coils from ORIO. Then tried the MAF from other car and that fixed it. Ordered a new MAF from ORIO and put it in that car and its been fine for a month.

Carfixer, Did your MAF sensor throw a code? The code that keeps coming up is P0300.
Thanks for the info.
