Default 94 suburban full throttle in park and in gear no power revs to about 1500 rpm and sto

When it is in park and I put the peddle to the metal it just is a real low pitched sound and just revs up to about 1500 rpm and stops sometimes it drops and goes back up and just does that and in drive I cant even give it half throttle without it doing the same thing and starting to shutter and act like it wants to die but stay at a low rpm and not want to accelerate at all and it will not go up hill faster than 15 or 20 mph even on slight hills if you kniw what coukd be wrong with it please let me know

Hi!
  • Do you know when this behaviour started?
  • Did it progressively turn worse or did it suddenly not wanting to play ball?
  • When was the last service performed?
I am no expert on your vehicle but I'll gladly help if I can.

When was the last time you changed your fuel filter for starters?

hello!
sounds like a collapsed catalytic converter! in park, you rev up the engine but as soon you put it in
drive has no power!
remove the O2 sensor in front of the catalytic converter you take for a ride or get back the pressure gauge
and install the gauge you should have very little pressure but if you have high pressure you have a
collapsed catalytic converter! bad cat 🙀🙀🙀🙀!
good luck!
