Hey guys I recently installed an inline pro turbo kit with aem ems. I got it tuned a few days ago and starting today my a/f readings started to jump from 15 to 16. I'm worried that my car is idling really high. I guess my question is that what could be the issue?

Thanks

 

when I had my Vortech, my AEM wideband would jump all over the place at idle, but tried to stay around 15 or so.

 

its weird it stays around 13 - 14 then few seconds later jumps from 14 - 15 and then jumps around to 15 - 16

 

when it hits 16 theres a little vibration from the engine, its like a little rev

 

My car idles at like 12 when really cold, but when warmed its pretty much pegged at 14.7, at idle the motor is under lil load, what does it read WOT

 

that's normal.. you also want to be around 15ish, when cruising low rpm..

 

Oh I see, I was just getting a little worried, because before I noticed that I was idling around 12 - 14.9. It just started getting higher and higher. What does WOT mean?

 

Wide Open Throttle. You should be hitting 11, when stomping on the pedal. If you're at 12 at idle, then that would be a problem. It'll mean that you're running way too rich and you'd be getting like 5mpg

 

Oh sorry I forgot to mention I only hit 12 on cold start

 

So its normal to hit 16 at idle?
