<![CDATA[noisy acceleration]]>Hi,

Im not mechanically literate, but I have noticed that at lower RPMS my car has a very gritty and loud sounding acceleration (1800-3500). I was wondering what could be the problem and what steps I could take to determine the actual problem?

I have a 2002 rsx type S with around 160k miles on it. It has an injen cold air intake. I changed the air filter around 4000 miles ago(it still made that sound before changing the filter) and I regularly change the oil and filter with mobil synthetic every 3500-5000 miles.

I also have noticed a sizeable drop in mileage (360-380 miles versus 430 on highway) but this may be attributed to the age and wear on the engine?

again, im a newb so I apologize in advance if i sound...noobish.

thanks in advance

Kenn

The difference sheeran is that even when we didn't know a coolant hose from an exhaust pipe we knew when to stop yapping and listen.

Being in the field you learn that pretty early on.

The car has roughly 160k on it...could it just be the cat?

Ill check tonight if the catalytic converter is glowing after running it for a while tonight

Tried everything and we finally used a torch and got it out. Took about 2 hours just to pull the original and maybe 30 seconds to screw in the new one LOL

i havn't personally done it but i've heard of people doing it with success. It would be alot easier than pulling the o2 IMO. I've never had luck with those comming out very easily.

my god, stop drilling holes in shit or removing exhaust. Unscrew your precat o2 sensor and install a backpressure gauge. There is almost alwyas a factory spec for this. Please tell me you dont actually drill holes in shit your trying to diagnose???

If you had a bad cat youd more than likely throw a check engine light. Have you ever adjusted the valves on this car? Change where youve been getting your gas lately?

holy fuck...someone finally posted something that isn't fucking dumb!!!

you can get the exhaust up to temp by cruising for a while and get out with your motor running and check to see if the pipe before the cat is glowwing (best done at night) and if it is then your cat may be clogged. Another test is you can drill a hole in the exhaust before the cat and see if it runs better and if so mmost likely a clogged cat and get it changed and the hole welded shut.
