I have just started to have a problems with my PR5 when accelerating from a stop. I am getting a jerky, slow accelerating, especially in first gear. I have not had the money to go a repair shop yet, as I am out of work. I am looking for a place to start looking for a problem. Please help!

Lack of acceleration, chugging, hesitating, bogging etc. Could be caused by one of the following below.

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.
Incorrect ignition timing.
Cap and rotor.

I had someone look at it and I had a hole in the air filter snorkel tube. I replaced it, and it appears to be running better. Thanks for the assist.
