I have a h/c 98 c5 m6 in 4th gear on a 100 shot the car bucks a little, My af spikes rich from 10.5-11.5. Possible solutions not a good purge, low bottle (checked out), bad internitant ground, jets set at factory specs, I might go leaner on the fuel and see if that cleans up the AF. The only other thing I changed was the relay (after the detailer fried my last one from the detail stuff getting in there) Are there differences between relays?

Anyway I would like to know your thoughts?

 

No response?
