Hulknasty's 95 5.3/60e swap

[kewljay223]

Any idea why my speedo likes to bounce around alot? Speed sensor is brand new. Throws code p0608. Am i missing something?

what trans was in it before?? you said you swapped a 60e in. it didnt come with that? if you had to extend the purple/? twisted wires or add them if you didnt have them, make sure your connections are solid and that they are TWISTED all the way to the pcm or else it might be picking up interference from other wires and definately will provide interference to others as its a pulsing signal.
