I have a 2001 Infiniti I30, 106000 miles. I had the regular services performed and am noticing the car hesitating when I first start and take off. After a minute it runs fine and has no more problems and rpms are fine and steady. I had the sparkplugs changed @99k. I tried pulling codes no luck, tried seafoam no luck, checked battery and hoses nothing. Any help is appreciated

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

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Knock 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.

Note:If it doesn't apply disregard it
