Purchased new ht leads, spark plugs and a stepper motor for the Polonez. If that doesn't cure the slightly high (1200 rpms or so) and lumpy idle then I guess I'm gonna have to start looking for an MS DOS laptop with a serial port to hook up to the diagnostic port.

Interestingly, a mechanic who knows these cars (worked at a dealer and actually performed warranty work on my car back in 1996) told me that it's a good idea to replace spark plugs every 7-10 k km. Interestingly, that's also the realistic interval between valve adjustments. Welcome to proper 60's motoring in 1995.

Photo for your time. :D

Does this have a lambda sensor?

If so I ran into an interesting problem with one on my Lada.  There was no local ground for the signal line in the ECU, relying on the sensor being grounded through the case (despite being a four wire one, so it looking like there should be no need for it).  This wasn't a problem with the original AC Delco AC97 sensors...but they've been unobtainable for ages.  The modern Bosch etc replacements which on paper should be compatible obviously don't work though as the sensor is fully isolated from the case.

I chased this problem around for several weeks before connecting the signal ground for the oxygen sensor in parallel with the throttle position/coolant sensor signal ground pin at the ECU.  Problem immediately completely rectified.

Just figuring they might have used a similar system so it was worth mentioning.

Have not considered this to be honest. I'll make sure to investigate.

Was your Lads throwing a check engine (or equivalent light) through all this?

Cheers!

Ouch, hope the damage isn't too bad once you get it dragged home 

Temperature sensor split, thus pissing coolant everywhere. Walking to the motor factors now to pick up a replacement.

Yep.  The error it was showing was error 31, no oxygen sensor signal.  Basically because there was a +1.3V offset on the signal because the ground was floating.

Swede dreams are made of these

And fin. So the background to this purchase,  I posted a thread a month or so ago looking for a car for my in laws, they hummed and hawed over the few I sent to them, then last week they phoned to say they were going to buy a 63 plate Peugeot 208 from Arnold Clark for 5.5 fuggin grand. My wife offered them her own higher spec lower mile 208 for half the price. They snapped her hand off for it, she now has my Saab 9-3 floppytop which left me needing some wheels. I wanted something similar to the Saab, Nice comfy auto with a bit of grunt for cruising to work.

This thing ticks all the boxes. That trip home was genuinely one of the comfiest drives I’ve ever had ! Seats are mega comfortable, air con ice cold , sound system is unbelievable as well. Cruise on and point towards Scotland.

I was hoping to come across another Saab for sale this week, I really like the 9-3. I’ll settle for the other Swedish slab
