1693 is a Companion Code . This lets guys like me know that another code exsists in either the ECM or PCM.

Need to have it scanned if it won't come up on a key method trick.

your juice with attitude is prolly causing that. no big deal, its just because the juice is adding more fuel and it doesnt know what to do. me and my buddy's truck throws that every now and then. still runs top notch!
