Just wondering. When my car is 200 degrees it dogs bad and I know it got tons of power. It only does this when the temp rises alot But when it stays around 160-180 degrees it acts normal. When I got on it from a 45mph role my timing was retarded greatly. And I don't have my pcm tuned yet with the lt4km but will get the pcm tuned and lt4km solve my problem. It just started doing this after cam install which I am begining to think this is natural.

 

Spark retardation because of knock does not light the SES.

 

what would trigger the ses light then would bad o2's do it.

 

Bad O2s can cause the SES. The thing is, when you get the SES, you want to have it scanned so you can find out what it is and not guess.
