Swap backfires on idle and on the way down from reving. Timing is off but I cant find the timing diagram for the ZC or the firing order. Im getting fuel but question is how much? I need pics of timing/firing order and dizzy wiring....thanks and Ill have pics of my car when its running as I have now finished my first official ZC swap from a DX...no CELS and a little bit of timing issues but I believe thats it....its about TIME!!!!

 

This is what I have for firing...let me know if its wrong...



1-on left(shortest wire)
2-above 1
3- on bottom
4-right
All these are going in order to spark plugs...let me know if they are wrong.

I believe you have it wired wrong. Take a picture of the front of the dizzy so we can take a better look.
According to the info that I have it goes like this.
Bottom left is the #1 (also has a C in a circle beside it)
Bottom right is #2.
Top left is #3
Top right is #4.
I'd say give that a try, and see what it does.
Also, I believe you have it too advanced.
Later.

 

Heres two more pics-


Let me know ...
How do I retard my timing back to normal? I have no idea and no bible to obide by...any diagrams or hints to time my car would be helpful

 

To advance or retard your timing you loosen the 3 bolts for the distributor and you can rotate the distributor back and forth as you will notice the holes the bolts go in are slotted. That will allow you to advance or retard it. However you will probably need a timing light to do so.

 

Got it...and the order that was last listed was wrong...I tried it and nothing-wouldnt even start, replaced it with my order and turns over fine right away. I think my overall timing is off, any tips on timing procedures? Lets see if I can improve my weakness...

 

it looks like you have the firing order wrong... but its kind of hard to tell from the pics.

it should be 1-3-4-2 where on the dist cap 1 is the top left, then go around clockwise. like this:

1 3
2 4

it looks like you have 1-2 soemthing something, i can't see the bottom half.

 

to check your timing, set your crank to TDC. there are four marks on the pulley, three in a group then one by itself. use that one. line it up with the timing marks on the timing belt cover. your cams should point in very slightly. Or you could just use a timing gun. I've done this alot to get my cams just right.

 

that helps...Ill try it. I think my plug order was completley opposite too.
