I recently went down thru and replaced head gaskets and intake gaskets from an intake leak that got into the oil on a 96 k2500 4X4 w/5.7L Vortec. It's all back together and running fine,, but the service warning light still comes on and reads this code. I scan it and take it out,, but it comes back as soon as it starts up. My question is how do I get rid of this and what is the timing supposed to be set on and how do I set it? it is reading 20 degrees but when i move it away back towards 0 it immediatly runs very rough and has no power.it seems to run fine @20,, but it still isn't right. Could I have the distributor/trigger a tooth off? any help would be greatly appreciated. Thanks in advance. Phil
