It is possible the catalytic converter (or other exhaust part) is plugging
up. The Haynes manual for that covers my daughter's 93 Accord has a test for
exhaust restriction, using a manifold vacuum guage. She has the manual in
her car, but the concept is:
1) note the idle manifold vacuum reading
2) open the throttle to bring the rpm up to about 2000 rpm
3) close the throttle and watch the vacuum guage
If the exhaust is clear, the reading should show more vacuum than at idle
and return to the idle reading in about 2 seconds. If restricted, the vacuum
will seem to "hang" where it was and/or gradually return to the idle setting
after more than 2 seconds.

The exhaust can also be checked by loosening an exhaust fitting near the
engine and blowing into the exhaust pipe (remember to wash the soot ring off
your face!) There should be little resistance to your breath. An old Corolla
my son had was so blocked it was worse than blowing through a soda straw. It
idles okay but wouldn't go anywhere any more. A similar check is to compare
the exhaust feel when you place your hand near the exhaust pipe and rev it
with a similar car that works, but that won't show up anything but a severe
blockage.

I had change the catalytic converter two months ago, after testing the
motor presure "compresion" and changing the fuel filter i would have some
direct responces.> "Fernando Olea" wrote in message
