Help is here! I had the same sticking trouble. Try this before starting anylegal action against Nissan. The problem lies within the throttle casing.The butterflyinside is gummed up with varnish and black gook from crankcaserecirculation. First, buy a spray can of throttle casing cleaner. All autoproducts places have it. Disconnect the positive cable from the battery.Now, on my 98'pathfinder I had to remove the 2 small hoses from the sideof the air intake duct to the throttle, disconnected the top on the airfilter housing, removed the large hose clamp which couples the intake ductto the throttle, and pulled the duct off. Unbolt the throttle casingfromthe aluminum air intake plenum to get to the other side of the casing. Layan old cloth under the casing to absorb any of the cleaner. Spray theinside of the casing and make especially sure you clean the butterflythoroughly around its edge. Just make sure you get as much black off asyou can. Now just work backwards to get everything back together. Thereyou have it. The difference in the pedal is amazing and you'll notice howmuchbetter the vehicle starts.

2001 Sentra 1.8 - It's been at least 6 months, and it's still like new. I guess I used a toothbrush, not cotton swabs as I wrote earlier. Cleaned all the way around the throttle body where the throttle plate hits. Not just the plate itself. Cleaned until all the black stuff was gone. HTH --Pete

Yes the problem isn't the plate itself, it's the throttle body bore being gummed up that causes the problem.

I cleaned it all, starting with the bore. Maybe I missed an area the first time.

Or like I said you may have other issues if it's already dirty again. The crankcase vent hose before the throttle plate is suposed to -supply- air to the crankcase for the PCV valve to pull the vapors into the intake manifold. If the PCV valve is plugged up, the crankcase will vent in front of the throttle plate causing problems.

Thanks. I'll check it.
