This things setting a Crank sensor code, how will that effect the running of the car?
A LOT. It's going to affect timing in every table as well as fuel injector timing. What did you do to the crank? You didn't swap PCMs or anything did you?

It's got new Diamond pistons on the stock rods and crank. I ordered a new crank sensor today. I did the Case Learn with HP and the light went out for just a few mins. and the car seemed to run better.
Soo...when you put the crank and rods back in did you check the clearances? Or did you just slap it all back together, tighten the stuff down, and call it a day?

I didn't do the work on the engine it was done at another shop.
Okay. Did they install new bearings or use factory ones? If the correlation between your cam sensor and crank sensor is off then that is going to cause issues. Did they use adjustable cams gears? Were the cams you put in regrinds, blank grinds?
If they installed modified cams and didn't use adjustable gears, I would be willing to bet that is at the core of all your issues here.

The bearings are the stock bearings reused, the cam gears are adjustible, and the cams are blanks that cam from Bates Engineering. I'm not sure if they degreed them or not and the one's that did it went out of buisness.
I ordered a new crank sensor from GM to see if that solves this.
A new crank sensor is not your fix. If they ground the cams themselves and left the cam gears at 0 or something, this is surely part of your problem.

Were can I find info on this, I've never worked on one of these I4's. Are Bates cam's not good cam's or is it you just have to degree them different? Hell I don't even know if the other shop degreed them or not.
Would you mind giving me call?
Every cam regrind should be degreed properly, which usually calls for the use of an adjustable cam gear on each cam. If the cam and crank sensors are not reading in sync you will get all kinds of codes and rough running issues. Pull off your valve cover and check, it's pretty easy. I believe they even have a run through of how to degree cams in the Ecotec in the Ecotec build book. It's worth buying to read or finding it posted up online somewhere.

You must like leaning out on shifts then....
Doing it right means spending the time to dial in both the VE and the MAF.

I have the book, anyone degreed the cams in the car? Is there a right up on it anywhere?
The LSJ build books says exactly how to degree the cams.
Tyler
Yeah, they do it on a engine stand. I wasn't sure if there was room, but now that I have it apart it looks like there will be just enough. I did find that the shop that did the install didn't have the colored links lined up on eighter chain.
They only line up maybe every 8 revolutions of the engine.
They start out lined up till you turn the motor over once.
