Cam swap, new opti, ckp sensor outta range...

[Wicked96Z]

I have a 96 LT1 with some minor mods. Just replaced my cam with a schneider very mild cam, my stock one was thrashed due to frozen lifters. This fixed my misfire problem but now i have a P0336 Crank sensor out of range and car runs like crap, no power and stumble on accel. Idles bitchin.i put a new opti and new ckp sensor in and still have this prob. I have rechecked the cam alignment and its dead on. Normal slack in the chain. First startup it revved up nice, after that it stumbles. The ckp sensor reads the same rpm as the tach and i have re-learned it. Anyone out there had this problem? Schneider said i would not have to tune it for this cam...Bout to ditch it for a truck.

re-check the opti and put the computer again, to find the error codes,

what size is the cam maybe u might need tunning pcmforless.com is really good!!

I had similar problems with my 93 lt1 and following these steps has it running good!
