We changed out the EGR valve and the EGR valve position sensor. We cleared out the stored codes in the computer and then ran another KOEO test. The only code we got was:

34 EVP/PFE High

We used a OTC4000E code reader. We have yet to run a KOER test because his tach is stuck at 3000 rpm for some reason. This would make it hard to keep it at 2000 rpm for the KOER test.

The car still runs great except for the rough idle and rich mixture at idle. Any ideas?
