I ran codes today on my mustang gt with a digital code reader (obd1) and did both KOEO and KOER and only came up with codes in KOEO...Codes 10 (Don't know), 11 (System Ok), and 85 (Either 3/4, 4/3 Shift Solenoid or Canister Purge Solenoid Failure). I'm trying to figure these out sense my car idle surges when in park after it's been warmed up. It will only surge maybe 100-200 rpms sometimes 300 rpms from 600ish - 950 ish.
No Check Engine Light either....
