Bad ignition coil?
I've had a rough idle on my 87 CGT for quite a while now, and after ruling out vacuum leaks, fuel pressure, etc., I'm thinking my coil might be bad. It misfires pretty hard when it's warm and when it's under load. I did the checks that my Bentley manual shows, and it's definitely out of spec. The secondary resistance should be 5-6K ohms and it read 7.5K. The primary resistance should be .5 ohms and mine bounces between .3 and .4. It's $60 with shipping, so it's a relatively inexpensive "test". What say you Audi geniuses?
