Thanks

your dealer can do it. it me be free if there is TSB on it.

The dealer is who I think started my problem. I'm getting the P0327 Code for the front knock sensor. I replaced the knock sensor and the wiring harness. I'm still getting the code. The problem started after the PCM was reflashed with the new GM updates.

If someone could shed some light on this I would be more than grateful.

Thanks

Question, if you do blow your PCM and you get another and O'reileys can flash it (but they cant't tell you where the 10-30 oil is <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" /> )

Will the car still start? I thought there was another device that would not let the vehicle start becasue of the anti-theft.

Ideas?

the dealer can only do updates, and check that what is in it is correct.. a 'forced' reflash will lock the pcm MOST of the time.

i had the same problem with the back knock sensor code. the code moved to the front when i swapped sensors so i replaced the sensor and got rid of the code for good.. try swapping them and see what happens, if the code doesnt move, then its the pcm or the wiring harness for sure

I've replaced the wiring harness already. I didn't want to have to take the intake back off. It has to be the PCM. If it were the sensor or the wiring harness it would set the code as soon as the car is started correct. It takes about a day and half before the code sets after I reset it with autotap.

I wish it was that easy. Knock sensors can fall out of spec intermittantly & cause ses. The same goes for the wiring. You need to diagnois the problem catch it while it is happening , not quess & throw parts & money at it. Maybe as simple as a poor ground? I've seen stranger!
