Check Engine Code

Hey Folks,

I have a 2005 TJ 4.0 and was driving to work this morning and the check engine light came on and the jeep starting bucking and jerking badly upon acceleration. I limped the managed to turn around and head home to check the code. It is P0335 which from what I gather is a crankshaft position sensor. Does this sound about right to you all? I ordered one from advanced to pick up later, however I am not sure where exactly it is on the motor. I have narrowed it down to 2 but could use your help in locating it exactly. Hopefully this will fix the problem. As a side not I started noticing symptoms about 2 weeks ago after filling up the tank with gas. The next morning when I started it, it would stall and did this about 5 times and then it ran fine. I thought maybe I put some bad gas in it and for the most part after adding some Heet and a new tank of gas things have seemed fine until this morning. Does it sound like the crankshaft position sensor is to blame?

Thanks

Basically if the PCM cannot read the position the crank shaft is in it will not be able to fire the spark plugs correctly, giving you the lurching/bucking and rough idle.

I have had the same problem for a few weeks now. I have just changed the PCV and added 1 quart of oil. I have live wire kit with .065 gap, hypertech. It is not the gas. I use to have these symptoms befopre I even installed the Borla exhaust and any other performance addon. but the shop keeps upgrading the ffirmware and that is it. One day I drove into a big puddle of water on the streets and let go the gas. Well it gave me the same symptoms but the next day it was ok. I am about to change the sensor too. but there are a couple tests that can be run to determine if the sensor is pooched but I dont know them.


Anybody else with the fix?
Is the PCV supposed to have oil going through it?
