What could be causing my 2008 Nissan Pathfinder to have trouble accelerating after slowing down or stopping, especially during rainy weather?

There could be several possible causes for your 2008 Nissan Pathfinder to have trouble accelerating after slowing down or stopping, especially during rainy weather. Some common causes are:

1. Spark plug issues: Faulty spark plugs can cause misfires, which can lead to poor acceleration and decreased engine performance.
2. Ignition coil problems: If the ignition coils are failing, the engine may not receive the proper spark and can cause misfires, leading to poor acceleration.
3. Fuel delivery issues: If the fuel pump, fuel filter, or fuel injectors are clogged or not functioning properly, the engine may not receive enough fuel to accelerate properly.
4. Wet distributor cap or rotor: During rainy weather, moisture can cause a short in the distributor cap or rotor, which can affect engine performance and cause poor acceleration.
5. Mass air flow sensor problems: If the mass air flow sensor is dirty or not functioning properly, it can cause the engine to run rich or lean, leading to poor acceleration.

It is recommended to have your vehicle inspected by a qualified mechanic to diagnose the root cause of the problem. They will be able to recommend the appropriate repairs needed to resolve the issue.
