Hi All,

I have a 96 2.5 TL with over 200,000 miles. The car has been kept up great, and I still change oil every 3000 and service it when needed. No problems other than the common annoyances mentioned in some of the above posts.

However, over the past month or so, i've noticed a relatively loud low rumble - noticeable over 30 miles an hour. It sounds as if the engine is revving high, but the rpm gauge reads totally normal. The gas pedal also feels less responsive. And it's more noticeable in the drivers seat than in the passenger seat...maybe this means something?

This is coupled with a 14-15 mile/gallon gas mileage. Granted I'm in stop and go traffic for at least 1/2 of my commute, but it seems a bit extreme.

Thanks for any and all advice!

start with the basics - plugs, filters etc. Have they been changed recently?

Is the engine setting a Check Engine Light?

Have you replaced the PCV valve lately?

When was the last time you replaced the fuel filter?

I understand what you're talking about, i think i might be getting to that point or maybe i'm just too careful about my car, when i step on the gas it kinda hesitates before it moves, i wonder what could be causing that as its most definitely not normal, the rpm kinda goes up to 2 and then rapidly drops to 1 and works fine from then, but the pick up is becoming sluggish, this is the first time i've noticed this and want to know if y'all know anything about that...

Thanks for the quick replies.

To answer:
Check Engine Light: Not on
Filters: Replaced recently enough that I don't think they would be the problem
Plugs: I think they were replaced 30-40 thousand miles ago - possible culprit
PCV valve: I have no idea what this is - so a definite no on being changed recently

What have been replaced recently are the O2 and secondary O2 sensors, and an EGR valve.

I'll try swapping out the plugs and post again if the issue persists.

Thanks again

seafoam..in your brake booster or your pcv vavle also you can add seafoam in your tank and your oil..it improves acceleration..if you plan on doing it heres a link

I don't know how I didn't see your post. Anyhow, BATTERY. Have it tested to see if it's your battery's problem, and check your terminals for corrosion. It seems to me that the negative side seems to love to get corroded on our cars.

~Cheers~

Kewl, I 'll post again on how that went

Definetely replace the PCV Valve. Costs around $3, and will take around 2-3 minutes to replace - a very simple procedure. When mine was bad in my old Accord, it rumbled, got me very poor gas mileage. I venture that yours is bad.

Teekay: I know you're new. Start your own thread if you've got a problem, as that migth get you better responses more tailored to your problem

hmm.. my car sounds like crap too.. i haven't changed the PCV valve in 4 years..

i have one coming at pepboys..

btw.. are there any other filters that need to be changed regularily.

i know of , air filter, oil filter.. tranny oil screen,.. fuel filter.. anything else?

pi1996

has anyone adjusted their throttle cable? and tranny switch cable?

Ken1997TL

I've tightened the throttle cable. You dont want to do it too much, it has to have a little bit of give.

Is your car louder overall? You might have a cracked exhaust manifold. It would cause a rumble and a loss of low end torue.

pi1996

i hope that's not the case.. because i had it replaced a year or so ago.. it has an annoying dull rattle when accelerating..
however, its only when i am driving.. when the car is in park and i rev it up, its fine..

i am changing my midmounts this weekend.. we'll see how that goes..

Has this car gotten the emmision repaired done under warranty?

It could be a cracked exhust manifold.

pi1996

yeah, the manifold was replaced under the extended warranty..

pi1996

replaced the pcv valve.. car is much smoother.. thanks for the tips..
