If set everything up normal the front rotor doesnt run but the car idles great. If i pull the rear rotor plugs & double the fuel values that the rear rotor idled on the front rotor runs like a champ... Any suggestions?

 

It helps to post which car and mods you have,so people can answer your question.

 

Figured out the answer on my own... I have a older set of ID1000s and 1 newer ID1000 and the new one flowed better then the other one so I just put 2 old ones together and now it works.
