New Intake Throwing Codes


Asked by Sep 16, 2015 at 09:07 PM about the 1996 Chevrolet Camaro RS Coupe RWD

Question type: Maintenance & Repair

Bought a new intake system online, installed it and it sounded great and no
codes. After the third start up threw the code that the system was running too
lean. Put the old system and code went away, was wondering if there was a
way to change the computer so that the idle doesn't run so rough and so it
stops running codes?

Sounds like a vacuum leak. HTH. -Jim


and or the mass air flow sensor...was it a higher performance system..if so , did they not bring that up???

The EGR riser hose has a hole in it so once I replace it and put the new intake back on do you think it will fix it? I have the original intake on and it runs fine and no codes. So once I get the new EGR hose do you think it will fix it?

Wasn't the MAF sensor just actually had that replaced the only difference between the air take system is the size of the pipe up to the throttle body is a lot bigger.

Yes, a faulty EGR system will cause poor idle/stalling. If the hole in the EGR tube is between the EGR valve and the intake it will suck air and lean out the mixture as well. HTH. -Jim


Ok great, I have the new tube coming in here in a day or two will update when put on. Thanks!


Sounds good. Yes, please keep us posted. -Jim


Alright everything works! replaced that EGR hose and put the new system back on and no codes! The engine at idle runs a little rough is there any remedy for that? Thanks!
