hi guys finally got the beast up and running (heads/cam ), it sounds awesome and idles ok. the thing that happened though, is the engine light came on after the car started warming up (probably going from open/closed loop whatever). im not going to get the car scanned yet cause im not taking it out. im thinking its most likely an O2 sensor, cause one of them was hanging in coolant for a few weeks what do you guys think? thanks as always.

 

Your HOrrible.. O2 SENSOR Writen all over it..
