I have an sr20 in an s13 and on a cold start, with my consult plugged in to my lap top, i see that once its warmed up (about 150F) the timing likes to stay around 16btdc at idle

And while cruising the afrs are rich. Between 12 and 13

BUT, if i turn the car off and back on... the timing goes back to what it should. At 15btdc with a little fluctuation at idle.

As well as the cruising afrs going back to between 14-15

Does anybody have any idea as to why this happening?
