Showing a picture of plugs aint gonna help you fix your problems. We already know your car is mis-firing. Do what has been suggested to you.

 

ok yeah i will. i was just seeing if this will lead to any other problem. appreciate it

 

my LS does the same thing, i'm running 2 1/2" exhaust but i know it's doing it because my o2 sensor isn't plugged in, i know this because it started doing it when my o2 sensor wires broke and i've been too lazy to replace them....i've also noticed more of a carbon deposit on my rear bumper.

 

start your own thread buddy

 

ok so i unplugged the o2 sensor and rode around for awhile and the "popping" went mostly away but pretty much went away. bad o2 sensor?

 

ok i know its been AWHILE since my last post. my computer crashed so got a new one. anyway i have done a compression test and ended like this:
cyl 1-210
cyl 2-209
cyl 3-211
cyl 4-0

yes 0 on cyl 4. so what should i take action on? what is the best way to fix this? i am still driving the way it is and its horrible but its all i have. will they be any scaring on the cyl wall? or what? thanks

 

Leak down test

 

ok

 

@oleskooljoker. Did you get your car fixed? I have the exact same codes that you had and I am wondering what the problem could be.
