This is with my phone next to the exhaust, is this how an Evo idles when it's cammed?



A couple WOT pulls is this A/F ratio pretty normal? Also Why are all three traction lights on?

 

yep that sounds like a cammed evo, also the afr looks pretty close too.

 

The car sounds just like mine (HKS 272s), for the wideband, is it running pump gas or e85?

 

Ya, Im still kind of in the dark about this car, don't know it's history or what all has been done to the engine internally (bought it from a dealership, and I knew more about it than anybody there). I got a good deal on it, but I need to go through everything. I'm gonna bring it in the garage monday, and go through all the fluids and check it out more thorough. I used to have a 1st gen 91 talon tsi awd years back, but this is my first evo. And its running 93 pump gas.

 

AFR is maybe a tad leaner than ideal for pump gas, but not too dramatic IMO.

3 ACD lights on means there's a problem with your drivetrain, by shorting pins 1 and 4 on your OBD plug you can get the error code which can help you in troubleshooting the problem. There's a thread on here explaining exactly how to do it, I'm not on my computer right now though so I can't link you to it. You should find it if you search for "ACD lights" in thread titles.

 

if thats pump gas I'd say thats to lean. Richen it up a bit to be on the safe side. You probably won't even notice any difference in power either.

 

Unless they did an acd delete and didn't mind the 3 lights on
