1995 Nissan Truck Repair Question
Hesitation upon a cold start
1995 Nissan Truck 6 cyl Two Wheel Drive Automatic 91,000 miles
I have a problem where my truck on damp mornings the engine hesitates, misses, bucks and fluctuates in revs between 1000 and 2000. At idle it appears fine but as soon as you step on the accelerator problem is back. It does it in the mornings specialy when its damp. Once it warms up, it works fine for the rest of the day. If you put the truck in neutral it revs fine place it back in drive and the problem is there. It does not do it all the time
Inspect and test all the following listed below:
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle 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.
