So here it is...
1986 GMC C1500
Stock 305 4bbl. When I start the truck, I usually let it warm up for a few seconds before I start driving. While the engine is still cold, the engine starts to ping. If I really give er, she pings even more. The only time it stops pinging is when she is warmed up (190 degrees). Then I don't hear anything from her. Has anyone had this problem? Oh yeah, it's not the timing. It's set right.

Thanks,

Joe
