Re: 97 gp codes
The DTC of concern and probably causing the tach issue is the P0336 which is a crank position sensor range/performance issue. Not sure but it may cause the other DTCs to set so get that taken care of first as far as priority.
P0171 is a lean condition and a fuel trim DTC and P0402 is an EGR related fault. Flow too excessive.

Re: 97 gp codes
You're welcome.
We have a DIY procedure posted at our Tips & Maintenance forum. See link below. Click here Also, be sure to clear the DTCs after CKPS replacement and then see if the DTCs reoccur. Good luck.

Re: 97 gp codes
Funny a Bad CKPS would set a DTC isnt it? I've never had that happen on a 3800 before.
