About 4 months ago my truck started to ping while going up hill or trying to pas another vehicle at highway speed ...it never tripped a code or put the check engine lite on....a friend with a snap on scanner scanned it for me..key on engine not running and came up with code p1208(info on scanner was same as my symptons)...i changed knock sensor,EGR valve,Egr tube and left side exhaust manifold(tube rotted in manifold.)and a set of plugs. If anyone has run into this problem let me know...all help appreciated.......Thanks
