came on during after cam install test drive, Predator says no codes stored..anyone know what it is...it's the service engine light, not the SES light...thanx

 

FYI SES stands for Service Engine Soon.

It's more than likely the random misfire code.

 

yeah, it's the light in the tach...it's not the service engine soon light, but it does say service engine

 

anybody ?

 

random misfire or o2 code sjould show up though???

 

thanx for all the replies, but IT IS NOT THE SES LIGHT.......there's a light in the same panel as the tach that says "CHECK ENGINE"....that's the light I'm talking about, no codes,guages read normal, no missing as far as I can tell since I didn't run it hard, idles like it should with a 224 cam. I havent driven it since because of the shitty weather so I have no more info or updates

 

I had that too. Had to have the dealer reprogram the PCM for the new cam; basically a crank relearn ( which no hand held tunder can do ). Try a search on my name in the PCM section. Not saying that's your issue, but perhaps it will help. Cost me $78.

 

crank relearn ? why does it need it ? what's involved ?

thanx, but I still don't understand why I would need to do that ? I never touched anything to do with that sensor or the crank and I'm not gettting a code related to that or any code for that matter, just a light
