Replaced cam/crank sensors, didn't help
I have a 2.5L altima with 82,000 miles. Common problem, 0335 and 0725 codes came on, symptoms are a hard start and quick engine revving on the highway.
I bought two Duralast SU6364 sensors and replaced the original OEM crankshaft and camshaft sensors.
From what I've read it seems that this fixes the problem immediately. In my case it didn't, and the same symptoms still persist.
I also tried removing the air filter, and checking to see if that little hot wire anemometer that senses air flow was dirty. It wasn't. Doesn't seem like an airflow problem causing it.
I don't know what else to check. I also can not get the connector off of the new crankshaft sensor because of the way it is now rotated 180 degrees (thinking maybe it was a bad brand new sensor).
