				CEL with p1124 and p1126 with rough idle
			 
 
			Hey Folks,
 I have a CEL with p1124 and p1126 with inconsistent/rough idle.
 
 I have cleaned MAF and replaced fuel filter.
 
 I have had p1124 in the past couple years(3-4 times), cleaned the MAF and code cleared and does not return for 6-12 months.
 
 I have white/grey smoke on startup and above 3k RPMs....this is a new symptom.
 
 Any ideas on next steps?
