I thought these were L jet or even Mo(t)ronic but my memory is hazy.

@Verysleepyboyi may have an aftermarket boss somewhere if you're interested. Let me know and I'll have a dig.

Thank you - let me know what you have please

I seem to remember that early and late 944 have different offset and they're L Jet.

 

Here's mine, an '87 944S - the fragile one! Owned for more than 30 years with over 300k on the clock. All original, it is fucking not.

Still looks fabulous - that's the 16V version?

I have a set of cookies sat around doing nothing, but I'm in deepest darkest Cornwall.

Also I always thought all 944s were Motronic, and also mine was a fucker for idling when cold but I understand there's an idle control valve somewhere, which I never bothered to investigate as I lived at the bottom of a big hill and after a minute of climbing it was fine,

The cookies came off of this, a Feb 85 car in Kalahari Beige:

This is my current victim, looks like there is a secret society of transaxle perverts crawling out of the woodwork around here.

Your beige beauty looks very simialr to mine - but with the original "targa" roof, as opposed to the (in period) Halfords tin opener sunshine roof.

Send me some details of the Cookie cutters please (sizes/ condition/ offfset etc.), can always arrange shipping or a road trip if necessary

Well - one week in and already my first FTP in the Porsche 😥

Took it out for a local drive yesterday afternoon to see a mate, and on the way back along the A5, I heard a loudish backfire and then nothing as the engine decided to cut out on me. Luckily I had just enough momentum to roll off onto a side road away from the main traffic.

Under the bonnet, nothing immediately obvious, but it wasn't for restarting, not even a cough.

I had almost no tools on me so diagnostics wasn't really an option so it was out with the recovery phone number and a Truckofshame ride back to my local mechanic (who had rightfully gone home by this point)

Initial thoughts are either fuel pump relay (weak spot on 924/944) or an ignition system failure - but won't be able to do much to check until the weekend.

Not a great start to the ownership experience........

It still looks fit on the transporter though, so almost a positive!

Indeed it does - need to take all the (albeit small) wins at the moment!

Always worth having a spare fuel pump relay in the glovebox for these, or even a paperclip to jump the pins will do. Last FTP I had in mine last year was the fuel pump fuse had a crap connection to the holder - annoyingly only realised once I'd been recovered home, as it looked fine visually!

[Verysleepyboy]

It's all a learning curve, but yes a spare (tested good ) relay is on the list of must haves in the glove box!!

[Verysleepyboy]

Interestingly, the car started up fine yesterday morning (lumpy cold idle), warmed up to a nice smooth run but then after about 10 minutes went really lumpy and cut out.

No time to do much diagnostics yet but new fuel pump relay now ordered as first thought - or at least to have a spare.

Try running it until it cuts out. Then squirt some brake cleaner in the intake and see if it starts again. If it does, you know it's a fuel problem.

That's broadly the plan, just need to get some time on it!!!

Should then give me a clue if its ignition or fuel

Has the rotor arm recently been changed?

I had very similar behaviour on a Saab 900 where it turned out that Intermotor had the wrong rotor listed.  It worked fine for about a week, then one day I spluttered to a halt at the side of the road - it behaving all the world like fuel starvation.  

It would run fine for ~10 mins from cold after that before starting to cut out under load, and eventually stalling altogether.

I was chasing this for WEEKS before I found the old rotor floating around the boot and just tried it to see if anything changed...and it just worked.

I still had a spark when it died - it just wasn't strong enough.  So it managed fine when it was cold and the mixture was rich - but as soon as is started to lean off as the engine warmed up, it wasn't then strong enough to ignite the mixture.

Not saying that's the problem here, but wouldn't surprise me if a lot of the ignition system are the same or similar, so if you've got a spare floating around it might be worth trying!
