hooked this up to my 96 blazer and had no misfires what so ever no codes anything.. but the timing seemed a bit odd to me, maybe i am wrong. the readings where -25.** to -35.** according to the amount of gas i gave it.
is that normal for the blazer.
if you all rermember i am the one thats been having the problems weith the blazer not wanting to start when it wants to. it has a mind of its own.. i replaced the fuel pump the crank sensor.. i replaced the coil a couple days ago and it hasnt acted up yet but i am thinking it will.. just dont know when its going to act up
