Trying to find the closest longest lasting cassette to stock, and came up with two options. eSaabParts has one for sale but it's not SEM. Link here.

Second option is Rock Auto's NGK. From what I've been seeing, some have said NGK made the original cassettes. Link here.

I want the closest option to OEM/SEM obviously. My car has been struggling to start below 65F as of recently, occuring on multiple cold starts, it will either stumble and not start, or if I hold the key it will eventually stumble into a very rough slow start. This is the same car that threw a flashing check engine light when I floored it one rainy day. The spark plugs are however brand new and the type the car prefers.

My friends have said it's either starter related (starter is very tired sounding compared to two other 9-5's), fuel pump related (gas gauge doesn't work, unrelated but worth mentioning), or what I think is the DIC due to the CEL coincidence. My MPG has also fallen from 27+ to 26.0 which I find interesting.

Here's a link to three different cold starts.

Thanks!

In my book, the jury is still out on what’s going on with the transition from SEM to NGK and now to this new ”Saab Original”. Time will tell when we start to get some user data on the latest iteration. Here’s an interesting thread:


from the sound of things to me, your hard starting could be a number of other factors such as spark plug change interval, vacuum leaks, MAF sensor and so forth. If you choose to install a new DIC let us know which one you live with and whether or not it restored you’re starting to the average slow normal.

I don't think that's right. I think everyone is pretty clear on what's going on.

WVE was a US distributor of SEM products
NGK bought Wells
NGK became the US distributor of SEM products
SEM stopped manufacturing T7 DICs a couple years ago
Orio designed & began manufacture of a non-SEM DIC about two years ago

Your options are:

1. Buy a SEM/WVE/NGK DIC that was made before manufacturing stopped #55559955
2. Buy an Orio DIC that was made 2021+ #32022255

I've bought a red NGK DI from Rock auto last year. It came in a colourful NGK box.,, unlike the cheap corrugate box, SEM of old came in
And the DI has an SEM sticker on it :cool: .
I phoned NGK to ask about this they said they owned SEM for... some time now.
But what would they know :ROFLMAO:
Beyond that it's working perfectly for over a year now.

That Said SEM makes a wide range of Ignition products a reason for NGK to own it and it's products.
DI cassette manufacture in itself is Clearly a business with zero future possibilities.

So basically pick from the two I posted. I'm just afraid to spend the money if it turns out it was something else. I'm sure the car does need it- surely it's not fuel related because the car starts up quick when it's warm, it's only cold starts that are the issue. Today took three tries to start it, so it's only getting worse.

I bought an “OEM” Orio one about 6 weeks ago, it’s been nothing short of amazing. I bought the car and it had a Chinese knockoff on it, this one runs and even idles smoother. Great price too:

The '08 I picked up over the summer enjoyed a dramatically improved idle with a new Orio DIC as well. I had already replaced the motor mounts and was not impressed with idle quality, but the new DIC got it very close to very good.

Going back to your cold start issues, do you hear the fuel pump prime when you first turn the key to the on position before you turn it to the start position? Second thing, You may be losing fuel pressure overnight. You can rent for free a fuel pressure gauge from AutoZone- check the fuel pressure on the fuel rail before, during and after starting. It should be in the 35-40 pound range

Sorry for the late reply, I didn't receive an email for your comment, but I can't say I hear anything particular but I believe a few noises can be heard. I was told to wait longer to start the car and see if that changes anything but always turned the key to the on position, waited for the system check to clear, and turn off the ACC. That should be enough time but maybe I can swing by tomorrow and grab one.

I've noticed when driving, at really any throttle position, and even coasting, the car feels like it's stuttering. Just barely noticeable but no other vehicle I've driven feels like this, basically doesn't drive smooth. Very annoying because this can still be either cassette and or fuel related.

As for the code yeah I should get that looked at first.

Funny you say that, I just replaced the throttle cable cover. I assume there’s a plug I can clean in the mean time? It’s that or a vacuum leak which I assume is possible as those cruddy old pipes age.
