well it all started when i put that dam thing on it was fine then the mafs went bad i check it out and every thing is peachy cel gos off and then back on again everything is set up right and i have a bypass valve on as well . but to get to the point the AEM intake is putt'n on the light is injen any good ??? and i did replace the mafs and guess what ......... the light is on again and well does anyone know what the prob might be >

 

you make sure that you didn't put the MAS backwards? did you plug the MAS back in as well?

 

trust me its in the right way

 

How do you know the MAF is bad? Posting a pic of your install would be helpful for troubleshooting too.

 

i did a scan on it and got a new one you know mafs do go bad even on new cars im just the unlucky one who has been **** on

 

Yeah...I know they go bad. And I'm sure you don't want to hear this, but punctuation really helps get your point across.

I dunno though...it seems really unlikely to me that 2 MAFs just suddenly failed. The intakes themselves do little to modify air flow, and the fact that none of the FI Lancers, most of which still use their stock MAF sensors with significantly increased flow, have had failures. It's far more likely that either they both got damaged or the ECU code is misleading.

 

ecu that a word i dont wanna think about i will look into it thanks

 

Well...the ECU is what gives you CEL's so it's something you need to consider. It will only put out what it reads in, but the codes it throws don't necessarily indicate failure so much as irregularity. Did you reset the ECU when you installed the intake? It's possible that the ECU simply started throwing a CEL because of the change in air volume or velocity. I wouldn't say that's 100% true, and you may very well have gotten two failed MAF's, but if that's the case I think you could get a write-in vote for worst luck modifying a Lancer. Nobody's taking the gold from me in that category though.
