I just did a KOER test and it came up with this code:
Code 98 - Computer detected hard fault (EEC in FMEM or Failure Management Effects Mode)
The engine has been idleing a little rough and when I start the car it'll have a high idle. So far I've been assuming this is a IAC problem. Any ideas? I've pretty much replaced every sensor u possibly can.
