EGR question for 460
I have a 97 Ford F-250 with a 460, and it pings and surges under load. Someone on here told me it may be the EGR valve. Now I hear that there is aEGR position sensor,and a EGR valve pressure sensor. With no check engine light, how do I know which one too aim at first? Any suggestions would be greatly appreciated. Thanks.

Before you go after the EGR valve, I suspect you have a partially clogged catalytic converter. Disconnect the exhaust system upstrem from the catalytic converter and take the truck for a quick spin to test. You'll know right away if this is the problem.

to check the egr valve you need to start the engine, unplug the vacuum line. put a vacuum pump on the egr valve. apply vacuum. the engine should stumble or die, and the egr should hold vacuum. if it does then the egr valve is good.
