poor performance, lots of fuel

[princeandsheba]

I have a 1994 camry V6, recently purchased, with only 56,000 miles on the clock (verified). It is sluggish, and returns no more that 12-14 miles to the British Gallon, whereas my old 1992 V6, which I still have, with 177,000 miles, outperforms it in all respects.
There is no discernable mechanical reason for the poor performance of the newer V6, and the only difference between the two vehicles is the exhaust system, a unknown make of stainless exhaust, allegedly for a Camry on the newer car, and the true Toyota system on the older and more efficient vehicle.
Opinions, please. Should I switch the exhaust systems? Could this be the source of my problem? I am not looking for(too much)speed (Where can you use it in this law-ridden island?), just a better ride at a price a Pensioner can afford. Thanks for any advice.

If exhaust system install a vacuum guage on the intake manifold, the reading will drop as the back pressure builds up.

clean the mass air sensor, common problem and a good place to start. Have you checked the air filter as well?

also- hard to check...but knock sensors on the 1994 camry (presuming you have the 1mzfe instead of the 3vzfe) are extreme sensitive and will affect both performance and gas mileage

Do check the O2 sensor(s) also.

that's hard to say...throwing any codes? any previous symptoms? noises? how much power loss? etc etc.

it wouldn't hurt to post up a new thread with more details and see if anybody has any ideas
