Bought a 1995 940 2.3 Turbo with a known rough idle/running issue as a parts donor for my 940 of better door cards, various clips etc.
Has ticket to June'24 and body issues just pieces of flaking lacquer on bonnet.
Too good to scrap once I've got the bits I need, so was going to do a quick fault find to see if I can get it running better and keep another on the road for someone who wants a cheap motor.
Below is link to thread to previous owner had started, and highlights actions taken so far:-

Just want a steer on best way to start, I have spare known good spark plugs/Bougicord leads. Lamda light is on dashboard, car came with code reader that plugs into base of armrest, I believe this may be one from another user on here??
Should I clear codes now, then do a fault code code check, or should I replace plugs/leads first, then clear codes and recheck??
Cheers
