  1. Last night on my way to work about 2-5 minutes after I had been driving my C/E Light came on. My oil pressure was normal and my car was not running hot so I went to work and back home. Today I did a code scan and came up with codes 311 and 314

    311: Thermactor Air System problem - no operation durring Engine Run Self-Test (Bank #1)

    314: Thermactor Air System inoperative durring Engine Run Self-Test (Bank #2 with dual oxygen sensors)

    What is the Thermactor Air System? And how can I fix my problem? My car seems like it runs fine, little bit of an idle problem but its always had that, and it has only stalled on me once but it did that when it was bone stock before.
  2. That would be your smog pump. Either bypass with a different belt or ditch the entire system.
  3. my smog pump is completly gone... so I need to unhook the battery to reset the computer? I took the pump off last week and didn't get a code until today
