hi. i have yet another problem. I recently replaced the coils/plugs/wires on the car. its an 05 with 94k miles on it. this noise comes from the engine area and is pretty loud. for some reason the noise wasnt as loud when i recorded this video but it sounds louder than this. The car DOES have a clogged cat but the car has and still is misfiring before the cat became clogged. anyone know what the problem is? I am changing the cat and exhaust this weekend so i highly doubt that the cat is causing the noise.

Ill list the problems:

car picks up real slow, rough idles and misfires, engine drops below 700rpm constantly.

Coils, Plugs, Decat.

 

Can't be coils and plugs cuz as I stated I just replaced em. Highly doubt the cat is causing that noise.

 

Did you make sure the leading and trailing plugs were in the correct spot and the wires were to the correct plugs? Sounds simple but happens all the time.

 

yeah i made sure. dont know what it is but its getting worse.

 

A stethoscope is useful for pinpointing noises. http://www.harborfreight.com/catalog...&q=stethoscope
