Changed my cam & crank sensors and now my idle is rough and will eventually stall. Sometimes when slowing down and coming to a stop it will stall. If I drive it at speed it runs fine then once tou take your foot off the gas and come to a stop it will rough idle and die? When first started it will idle 750rpm then jump to 900, then fall to 500 then jump up, you get the picture.

Also when you put the sensor in the engine, the O rings just barely touch the block. Is this normal? Seems like it should go about 1/8 further in

What could it be?

 

If you didn't use an OEM or Hitachi sensor then that's probably what's wrong.

 

know where to get these or specific part numbers?

 

OEM angle head 23731-AL61D

OEM straight head 23731-6J90B

Both are superseded by a newer revision that has a metal cap in the end but the previous revision is a lot cheaper and still good for 100k+ miles

Hitachi was the OEM manufacturer for the early revision ones and can be gotten for even cheaper under their self-brand.

I think CPS0008 (angled) and CPS0005 (straight) are the correct part numbers.

Edit : CPS0006 for the crank sensor or OEM 23731-AL60E

 

do you think the Hitachi from Rock auto will work?

 

Yep, they were the same ones that came factory installed on the G35, they last about 100k before they finally start getting oil inside the sensor and fail. The newer revision with the metal case supposedly doesn't have that issue but they're VERY expensive.

 

 

Could be several things. If the "O" ring is not in the block cavity, the sensor is not all the way in. When the retaining bolt is tightened to the proper torque, the flange of the sensor should sit flat on the head block all around the bore. I had to remove the throttle body to access the driver side sensor. If you did that, did you use a new throttle body gasket and torque the bolts to specification? Did you disturb the throttle body butterfly valve when the throttle body was removed and electrical connector was disconnected? If so, you need to do a throttle body re-learn procedure. If you do a search you can find the procedure, it is posted on this forum somewhere.
