I did get a code like this before... never really fixed.. and I've been having pinging problems FOREVER !!
It is getting warmer again.. and the pinging gets worse.
I wonder if it is related to the EGR valve.
i did post about EGR and pinging at old CEG forums and it was a MESS.
some sid they were related and others disagreed.
Let me know if u have any pinging on a hot day, going up a hill at high RPMs.
EGR valve is your problem. The EGR valve is used under light to moderate loads and is essentially a metered vacuum leak. It uses spent exhaust gas which is inert to cool the combustion cylinder because the EEC is advancing the timing so far trying to get better milieage and better emmissions. REPLACE THAT BEFORE YOU DAMAGE YOUR ENGINE. Here are the part numbers for the valve and gasket:
F5RZ-9D475-B List $82.38
E6AZ-9D476-B List $2.07
FYI www.fordpartsonline.com has the valve for $44. It would take a novice no more then 10 minutes to change.
I offer PnP Heads for all durtec's details at PnPheads.com or jesse@pnpheads.com for details.
