One tooth on the crank gear is 15*, one tooth on the cam gear is 7.5* (24 and 48 teeth respectivly).
That'* a lot.
On the harmonic balancer you need to check that the rubber between the inner and outer is still sticking and isn't ripped.
Don't get your spirits down. I put over 60 hours into my timing over two weeks to find the real problem. I got rewarded in the end with a car that starts with just a tap.

Well, If you've got it installed 15* retarded and the PCM tried to advance 20 degrees everything is going to be wrong.
The PCM uses the CTS to help determine SA, so the temp of the engine is going to change hos it runs if the gears are off.

I just dont see how I could be off at all though. I hear it is possible but if the camshaft and crankshaft didnt move at all when I changed the gears and chain I just dont see it being off. Never know I guess though.

I wish I knew who the engineer at GM was who decided to put a plastic snap in magnet inside an engine. I cant believe I am going through all of this over a 9 dollar part.

LOL I broke one too. I found some guy on another forum who filed the back off his and used JB weld to put it through the cam sensor hole and stick it to the sprocket. He said his is still working 5 years later. I wasnt that lucky after about 5 hours of trying to get it to JB weld in there.
