after a weekend of road racing (133 miles and 27 gallons of gas all on the road course @ 4.9 miles per gallon!) i went home and atap'ed to see what the S.E.S. was for. i found P0300 for the cam (multiple misfire) and thats no biggie.
a P0171 / P0174 for lean bank 1&2 (Ltrims are at 25.0% - looking to get LS1 edit tunning to fix this).
a P0336 crank position sensor range/preformance. guess i just need to replace it just to be on the safe side. never seen this on my car before.
and last but not least a P0410 secondary air inj. system malfunction. this is also a new one. is the pump bad? should i wait till it pops again to try and fix it? or is it usually something that once it sets a S.E.S. it will normally fail?

 

P0336, never seen that one either.

P0410, I've had that one. I cleared it and it never came back. I'd not worry about it unless it continually returns.

you have to do a Crank Position Relearn on the tech 2 for the P0336. swing by when you get a chance, and ill have mike do it.
