I have a 2001 Nissian Frontier runs good till engine warms up then starts to sputter everytime I give it gas.I have changed the fuel filter and added gas treatment.But none of that seem to help.

No codes showing up on the computer (EGR, TPS, etc.)?

Is the timing OK; distributor lock nut tight?

Catalytic converter clogged; does the exhaust seem free flowing when revving it?

How many miles? Does it need other tune up items (plugs, wires, cap, rotor, etc.)?
