engine barely accelerating

If the car has a manual transmission is the clutch worn out? Do you smell a burned out clutch smells like burning brakes? Likewise if automatic transmission perhaps the transmission is failing check the automatic transmission fluid level. I wonder if the fuel filter is clogged or the fuel pump cannot supply enough volume of fuel? Could have a slipped timing belt or a restriction in the exhaust (plugged up catalytic converter).

Even though you bought this car around five months ago and if i was on this site then. I would have told you TO WALK AWAY FAST. We both have the same year, make, model and engine. Mine ahs been a piece of junk. I have to keep it for the time being and that is i have put in so much money.

check the oxygen sensor.
