Re: service engine light on
Diagnostic aids for DTC P1345:
1. A loose CMP sensor causing a variance in the sensor signal. 2. Excessive free play in the timing chain and gear assy. 3. Incorrectly installed distributor-1 tooth off in either direction. 4. Loose distributor rotor. 5. Loose or missing distributor hold down bolt.

Re: service engine light on
Yes,
I did have the distributor out. I replaced the head gaskets and intake gasket. I thought I hade the distributor on top dead but I must be off a bit. Didn't have any service code before tking the engine apart. I must have the timing off like you say. I will also check my connections on the crank sensor. I did find an older post from 2005 that helped me out. It had a lot of info on this. Sound like that guy had the same problem after reinstalling the distributor. I haven't had time to look at it all week. I am going to try to get at it this week. I will let you guys know how I make out. Thanks for the help. Vinny.
