I found that when I step on the gas the motor is weak and makes a lawn mower noise. I pulled each wire out to see if it gets worse or stays the same to determine which one is bad and found out it was #4. I tried changing all 4 spark plugs and wires but the results are still the same. It has done this before but a spark plug replacement solved it but not this time. What are the possible causes? Bad distributor maybe?

 

fuel injector maybe? check that, same shit happened to me.

 

Coil?

 

hey dude you were right. haha thanks for suggesting it.

 

Burnt valve

 

cool, glad you figured it out
