I have a 95 blazer with a 4.3 vin W replaced cap, rotor, plugs, when I got to wires noticed that the left bank 2-4-6 was in order front to back. then on the 1-3-5 side they werent That is why I'm confused I did them 1 at a time and am sure the order was 3-1-5 front to back ! idoes anyone know this to be true ? the reason I am questioning it is that it still runs terrible! Thanks for the time or any advice anyone could give

 

The firing order is 1-6-5-4-3-2.

swap the 1 and 3 and see if that doesnt smooth things out.

 

The cap should have the numbers on it. If it does not, it does indeed go 3, 1, 5 on the driver side where the wires connect to the cap.

 

Thanks guys thats what I thought ! it is smoother but I must have a egr clogged or somthing its blow out black soot on the driveway while idling ! Wet Black Soot [>:]
