Just emulate what Dave's pictures look like. The spark plug wire numbers are located in the plastic spark plug wire channels. They are very small numbers with a circle around them deep in the channels. I took a picture Of the numbers in the channels, then blew them up so I could see them clearly.

Jono and Klink have taught us that misfire at idle could be related to spark plug gap. Make sure your spark plugs are gapped to 1 millimeter

Hi

...and as mentioned in your other thread, old motor mounts can make it FEEL like a misfire, even if there is not a misfire. Check them as shown in the photo below, if they are not recent or new.

Hi Dave
and thanks for helping me out

I have checked the distance between the engine and the lower crossmeber as shown in the picture measured to about 23 mm Looks like both engine mounts are replaced with original ones

Have also checked if all the ignition cables are properly placed shown in the picture
Controlled Battery Cables cleaned battery terminals and tightened 10 mm cable going to can moduls.

Have removed the battery pole and reset all the control units for 15min after that, then idle got better in the park and in the drive and motor pulled much better than before but not 100%


I drove home after work so the car behaved very well but then suddenly it began to chase at idle again

Im still wating for Code reader


Have checked the production date on the throttelbody it is from 1994
I think I have to send to the workshop for inspection and repairs
