Sometimes my car when started will sputter and jerk and not accelerate. If I kill it and let it set for a few minutes it will most of the time start up and run perfect. 4 months ago I changed the mass air flow sensor and all O2 sensors. Plugs and wire have been changed about a year ago. Any ideas?

Inspect and test all the following listed below and get back with some results

Catalytic converter.

Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
