I did the conversion as well with new tfi. dist. champion plugs and the 8mm wires. I completely removed my egr valve and covered it with a plate. I had my timing set at 10 degrees. It starts and runs great no problems, but I have the pinging also around the 35 mph mark and when I hit the gas a little hard. I was also told to replace the egr valve, which I haven't done yet. whutmore let me know if it fixes your problem. I was thinking about going down to 9 degrees for the timing, thats what stock is? I am going for my echeck tomorrow morning, and I really hope it passes, if not I have to wait till Jan. and then the car will be 25 yrs. old and it won't need an echeck.... The pinging has me concerned about passing the test.
