My car is not running right I'm pretty sure it is miss firing cylender that is what it sounds like. So I can pull the spark plug wires off on the first 3 cylinder the motor doesn't change tone but when I pull the 4th one off it dies but I am getting spark in the 3 cylinders because when I do pull them off it sparks while pulling the spark plug out? Need some help thanks

For got to put this in but I just bought the motor from tiger japanmotors
 
Well if it is getting spark to all 4 then you need to check to see that your getting fuel, also check your CAS, your ignition timing might be off, play with your CAS and see if anything changes.
 
CAS cam angle sensor, it is the round thing on your head on your intake cam, on the opposite side of the cam gears, there will be two studs holding it onto the head, if you loosen those studs you can twist it from side to side, you really need a timing light to get it dialed in right, but for now you can play with it a little and see if your problem improves, if it does you more than likely found your culprit.
 
Double check the spark plug locations are right, don't just go off of what came to you.

Also make sure the CAS is good. You can loosen the nuts and just twist it to see if the tone changes for you.
