Well a while back i was having a problem of alot of pinging after 4000rpm. I went back and changed the timming according to the marks on the balancer the timming was at 14deg. I set the timming back to 11deg. and now around 4500rpm it almost sounds like a miss, you can feel the car lag a second. Anyone have any ideas? It's a 95 cobra cai,o/r x, flowmasters, egr delete.
