Okay so codes 21, 31, and 51

21 - I have a brand new o2 sensor
.....so im not sure there

31 - is the afm correct? Now I've read the FAQ section on adjusting. However when you say the screw has to be a certain distance you mean from the top of the screw to the top of the housing or ? I could use some more insight on this one.

Thanks guys

Well, I'm not there to look at it for you so get your ass moving and do what makes sense (inspect the connector, wiring, sensor for crap stuck to ir, rattling noises when turned, bad gasket).

There was another part in that thread which said NEVER TOUCH THIS SCREW! That thread is only there so you can reset the screw is someones f'ed with it. At any rate, even if someone f'ed up the fuel mixture by dicking around with stuff like an idiot it still wouldn't cause a code 31. RTFM for diagnostics on the AFM.

I've checked all that. And I read that as well however the cap covering the screw is missing. So there is another cause for code 31?

Code 31 is an electrical failure. Nothing to do with the housing or trim screw.

Oh god... sorry. mixing up posts.... Just trying to check in while dashing from one place to another.


Forget everything except that 31 is an electrical failure. Resetting the idle/bypass air screw isn't going to fix that. Test the AFM as detailed in the TSRM.
