Three things.
\015\012First, you need to check the MAF sensor for contamination.
\015\012Second, check fuel pressure, if you dont have a gauge, autozone and Advance have them on their tool loaner program.
\015\012Should see 35-40 psi with key on engine off, cycle key a few times, if it takes a while to build up, replace filter and retest.
\015\012Third, possible convertor blockage, easiest check is to remove the 02 sensor and try to start with the hole open, if it runs, then that is it, specs allow for 2-3 lbs of back pressure max. That means if you can hear pressure escaping, it is a problem area.
