need help please I have an 96 lt1 camaro a4 I just install pacesetters longtube headers mangaflow catback fuel filter new spark plugs and wires it also has cai and under drive pullies it ran good for about 4days now it has a rough idle also its showing a code for the o2 senors I know thoes will have to be tuned out and one for missfire just want to know if I get the computer tuned will that fix the rough idle and who does a good tune for a good price

 

You might have just burned a plug wire. Or if they are coated headers the coating can screw up the o2 sensors in the headers. What o2 code is showing rear o2s or the o2s in the headers.

 

im voting burnt wire

 

They are coated headers and I think it's showing the code for rear ones also I check the wires and you was right one was burnt thank's for the info and if I get a tune will I be able to tell or is it a waste
