Loss of power

Just recently i have noticed an almost complete loss of low end torque. It just happened two weeks ago. I dont know why it happend, but it was really sudden and i dont think there is a major problem but i would like some suggestions on what it could be.

Things to think about
- Just changed oil -Q advanced
- bad tires
- have been using gas from the same station for the last two weeks. - Amoco Ultimate
- I have used fuel injector cleaner.

What octane have you been putting in the car? Not only do i have an RS but an integra and when i put low octane fuel in it i notice a power diffrence. Maybe check your Spark Plugs, might not be firing the right way.

bad tires wont cause a loss of power...how many miles are on your car? any CEL?

have you checked the oil?

what engine..trans?

Yes i have checked the oil, and have already said that.
the gas was premium. I always put premium in the car becase is says to. but the spark plugs are worth looking into if i could only find the other three.

honestly, the "back" spark plugs are a NIGHTMARE to get to..you have to practically take the top of the engine apart...thats why most places will charge a Ton for a tune up...

the plugs are under the intake manifold...

has the car overheated at all recently??

if ya can get to them try and check your plugs and wires.

a bad plug or wire, or any misfire issue, will trigger a CEL...i had a cracked plug that WAS firing, so i felt no difference, but i still had a CEL

Thanks yall, that is really good info to know. but i Think the Problem was just the gas. It is working better now. But I have another question.

Unfortunatlly i have an automatic, and when i put it in reverse i hear a short buzz an then a ping that sounds like hitting two metal poles together. Have any idea what that could be?

does it do this when putting it in drive also? I hear this noise also when putting it into drive and reverse, just without the metal ping at th end? Someone told me it's supposed to sound like that but i doubt that very much.

Also try changing your fuel filter...it could be clogged.

The buzz is normal coming from the solenoids that redirect the transmission fluid to shift into the appropriate gear. You can make that noise with the key on and the engine off if you shift between the gears. The metal ping is another story.

Well what should i do about the ping. Should i take it to get looked at or just live with it.
