Did a KOER test came up with these codes:

172-hego system lean right side

538-insufficent rpm change during koer test

632-overdrive cancel switch not changing state


truck at low rpms sounds like it misses but is fine driving!

any ideas?

-95 f150 straight 6 (auto)



KOEO TEST:

-172
-173
-327
-332
-334

So iam thinking i should be looking at the wiring for the EVP sensor...
