Just installed headers ory and cam this past weekend and had Justin build me a new tune but now it throws a p0141 and p0161 heater o2 code for the rear but I was supposed to have them tuned out is there something else that could cause this ? also getting a random misfire code every once in a while is this normal ?

 

He more than likely didnt completely disable the rear O2's if you are getting those codes. Email him back and let him know.

 

that's what i was thinking i hate to bother him again I know he is busy I'll get in touch with him though Justin and Jenna have always been easy to get ahold of any ideas on the random misfire code is that maybe the computer still learning the cam maybe ?

 

He may need to redo the tune. If have a random misfire its from the cam more then likely.did take injectors out or replace them with bigger ones, did you take the intake off?

 

Justin says I need to try a case relearn so I am going to try that soon as I can get back to my buddy's shop says he can do it with his hp tuners software
