I've got an acceleration problem with my 2000 Sentra that I can't seem to figure out. When you try and make it accelerate (either with the gas pedal or at the throttle body), the engine bogs down and loses RPMs immediately.

So far, I've replaced the spark plugs, fuel pump/filter, throttle position sensor and even the accelerator cable, and have made no progress at all.

Anyone have any ideas on what could be wrong?

 

Cold Air Intake, Performance Chip, and Exhaust System will add at least 40HP all together.

 

Is your check engine light on ? What engine?
