EEC-IV Code 67 ???
Noticed a high idle this week. (1200-1300 RPM) High idle sticks around until eveything is good and warm. 10+ miles of driving. Then finally drops to normal 800-900 RPM. But my low end torque is still gone. Also noticed a strange resonance from exhaust during low end acceleration or under load/climbing a hill.
I pulled codes last night. New one to me. Code 67.
KOEO Code 67
Continuous Memory Code 32
'87 Bronco II
2.9 EFI
5 Speed Manual - Mitsu
4x4
Suggestions on where to start?
Thanks!

The code 67 is most likely due to it being in gear when the test was run. The 32 is an EGR code. You should really run the KOER test, they should be serviced before continuous codes.

Yep! I'm a bone head. Must have been in gear last night. That's what I get for pulling codes just before bedtime. 
KOEO test during lunch today was code 11.
I'll do the KOER tonight when I get home.
Thanks again.

Finally did the KOER test. Code 11 = Pass 
I think I might have a bad injector. I took my problem to the 2.9 forum.
