Some EEC questions...

So I pulled some codes from the 88, there are two that I'm not sure about how to fix. First, KOEO code 67 neutral drive switch/AC input high. What is the fix for that? Second is CM code 34 EGR insufficient flow. Is this a bad EGR or just needs a cleaning? Car has 103,000 miles on it, not sure if the valve has ever been replaced. Also, how do I clear the codes with the jumper? I know I read on here somewhere but cannot find where? Thanks

Was the AC turned on when the test was run? If so, ignore the 67.

Pull the EGR valve and see if it is carboned up. Also be sure it opens with vacuum applied and the vac lines from vac manifold to EVR solenoid and solenoid are intact and connected.

I did have the heat on defrost and floor, so that should be running the A/c compressor if it's like most other Fords. So the test should be run with no hvac turned on then, I have the EATC on mine so next test will be with it off. I'll pull the EGR and give it a good cleaning and once over

You can erase codes by disconnecting the STI circuit while the CM codes are being reported.
