rattle coming from under hood

njstang · May 1st, 2008, 07:25 AM

Hey guys I'm getting a rattle / ticking noise coming from my motor when I accelerate. No CEL or anything, it almost sounds like an exhausts leak but I know its not bc the car was doing it before I installed my new exhaust. Any ideas? At idle its fine and the car seems to be running great, so I don't think its a mechanical issue, any ideas?

sea foam it.

probably head tick

Oh wait I think I know what it is lol my front drivers side 02 sensor is only half way screwed in, maybe it is an exhaust leak lol

If not, you may want to check your COPS

03_StangGuy · May 1st, 2008, 08:57 AM

is it a high pitch tinging sort of sounds, not very loud? I have a similar sounds. Andres wuts the COPS? Hmusn, hos does sea foam help a head tick? and what cuase the head tick?

cops = coil on plugs kinda like spark plugs
sea foam cleans your motor which may stop the tick if it is due do build up.

and you should probably screw that 02 sensor in all the way and see if the noise goes away first.

No its really not a loud tick and its not high pitched. I'm almost positive its that damn 02 sensor.

HMUSN · May 1st, 2008, 09:15 AM

only one way to find out.. it's fairly easy to get to.

03_StangGuy · May 1st, 2008, 10:51 AM

My cars an 03 gt, wit 35k on it so build up shouldnt be an issue. How long do the cops last?

HMUSN · May 1st, 2008, 10:53 AM

mines on stock cops at 101k though with no issues

03_StangGuy · May 1st, 2008, 11:05 AM

so that shouldnt be it, in due for an insoection this month so ill have em take a look.

Screw that 02 back in! A loose o2 sensor can cause weird problems and a mpg hit. If could be a header leak too.

i have the same sound, its the o2 sensor not being connected right
