Hello,
My ol sentra is having troubles when she gets running hot after about 20 minutes. She begins thrusting, hesitating or jerking (can't pinpoint the perfect adjective) in the high RPMs of whatever gear I'm in. She runs normally through all gears when cold. She has a history of distributor issues and we've replaced the distributor only a few months ago (with a used part) after we had a very similar issue before. So far we have replaced the cap and rotor with no improvement. Should we replace the distributor again? What could be causing them to fail?
Thank you

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

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.

Holy smokes!
Will test as much as I can, thank you for the list.
Can tell you that when this happened 2 months ago we replaced the O2 sensor, cap+rotor, cat converter, inspected the fuel injectors (to be good), ordered a new MAF, TPS, fuel pump, spark plugs, few hoses which had cracks and finally put in a new distributor.

Of course, then was then and now is now.
So I'll check again and post back.

Is the ignition coil the same as ignition module? That is located within the distributor?

Also, will I need one of those light gun things to test the timing?

Thanks again for the list.

The coil is different from the ignition control module -the coil produces the secondary voltages while the module opens and closes the primary circuit.

To time the ignition you need an inductive timing light
