2009 Nissan Frontier Repair Question
2009 Nissan Frontier loose power and hesitation
2009 Nissan Frontier 6 cyl Four Wheel Drive Automatic 15000 miles
After trany lock up in or out of o/d there is a bad lose of power. During slow acceleration @ 40 mph on a slight up hill grades, keep depressing gas w/ no response the truck starts to skip or lurch then it will down shift. I have started feeling that lurching at higher speeds now but is only present when accelerating up hill grades or when the truck is more taxed. The dealership is trying to say it's normal tork lock up " normal operation".
Lack of acceleration,chugging,hesitating,bogging etc. could be caused by one of the following below:
Possibilities: Inspect and test all the following listed below:
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Manifold absolute pressure sensor.
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
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.
