Hey all - I just put on an HPS CAI and my check engine light came on. Without going to teh dealership to get the readout, any idea what would have caused this? The MAF is hooked in right and so is the other sensor that was there....

 

umm... its hard to tell, but for me, there were the MAF and another one was that my car was running too lean. go to schucks and ask them to use an OBDII scanner. You should be able to use it for free. Other than those two, im not sure what ur problem would be

 

Did you reset the ECU?

You really need to SEARCH
