Hey everyone so lately my cars fuel trims have been way out of whack. One minute ill be idling and the AFRs will read 20 to 1 and after driving a little they will read back at normal (14's and 15's) then all the sudden they will jump back up to the 20's again.

Is it possible that a change in weather could have caused this? Anything else?

Thanks.

 

My car will sometimes idle @ 16 or so when I first start it cold but after I get moving it comes back inline.

You need to see what your fuel trims are @ to really get a good idea of what its doing.

I know you were tuned by wingz but do you have a way to datalog? A tactrix cable?

Depending what part of town you're in I could meet up with you and datalog and see what its doing.

I live in chandler but work in Tempe.

Good luck.

 

Yeah I live in Phoenix and go to school at ASU tempe campus... I don't drive the Evo there but I suppose I could drive it one day and we could meet up and data log it. I plan on getting a retune also for these cold temps haha

 

Bump

 

So no one has any idea what my issues may be?
