the other week i was about to pull my LS motor out of my sedan.. unplugged all the wires, hoses, and brackets... but because of the cold weather and the need for transportation, i had to reinstall everything back so i could drive my car..

the problem is, now i'm getting 2 CEL codes... 8 and 15... this a really annoying me cuz i am 100% sure every hose and harness is plugged back to its original place.. i even reset the ecu.. the codes did go away, but only for a day... now they're back and annoying me alot... any one experience this and how did they fix the problem..??

thanks

 

Possible loose pin fit now on connectors... sometimes happens when they get old.

I'd check there first

 

i'm thinking about putting that electric grease on all the harness connections in the engine bay ... hopefully that will solve the problem..

thanks
