I know this isn't a Chevelle, but it is my daily ride and I thought someone here might know.

I had a coolant leak at the back of the intake on my 98 Suburban (hear it's pretty common). After replacing the intake gasket I have a service engine code P1345, which if I'm reading right is a crank/ camshaft correlation error.

Question is, how do you correct this? Will adjusting the distributor timing help?

Thanks for any help

Rod,
If you had the distributor out, there is a procedure that has to be followed pretty precisely when re-installing it. You need to get the service manual and follow the correct procedure and then it should be ok.
Hope this helps,

Thanks Bill, figured it was something like that when I saw what the code was. Old school me just stabbed it back in at the marks like I would for the Chevelle.

You have to adjust the distributor. For this you will need a scan tool that displays the cam degrees and adjust it to 0. If it's reading something like 8 and you move the distributor, the number won't change until you rev the engine. I think 1200 rpm should do it. Just hit the gas, this allows the pcm to update and give you the new cam degree reading. Hope you get it figured out.

Actually I cleared it this morning without a reader. I got lucky and it only took two moves, I put a alignment mark on the cap and moved it about 1/8" clockwise, cleared the memory and restarted it. Sounded like it was cross firing slightly and the light came back on even quicker than the first time so I moved it about 1/8" past my index mark the other direction and bingo!

I will invest in the right tool soon anyway. I was thinking about one of the type that interface with a palm pilot. Anyone have experience with these?
