98 Frontier KA24 Mystery Problem

[240_Frontier]

I have been having a problem, the only times the problem occured was during long periods or idiling ( in which it idles itself to a stall) and during high way driving. And this symptom was like no fuel going into the engine, but after a pump or two of the gas pedal, it drives back to normal. I have replaced my ignition coil, distribitur cap, rotar, spark plug wires, and spark plugs. any ideas? please email me at [email protected]

if you nave a volt meter , back probe the o2 on the 2volt scale and watch it when this happens. see if the o2 is locking down above or below.450 volts.
