Is it possible you damaged the MAF while performing the work? Just a guess here but if you broke the box up without removing the MAF there is a chance the fragile wire that it deploys was damaged by vibration. I would try cleaning the MAF.

You probably wont believe me. Take it all out and put it all back in again. I bet you have a leak in the system. If there is any air getting in after the maf the car will act like this. I speak from messing this up a few billion times on my own car. Especially check the center big rubber links they look on and feel good all the time but they might not be set on correctly.

Unplug the MAF and drive the car. If it runs better, replace the MAF. If it still runs lousy, you have a big ol' intake air leak as JAAY suggested.

Absolutely agree on the unplug the MAF and see if that improves things idea. The car's DME uses the MAF's values to gauge engine load, and thus lookup appropriate values for fuel and ignition tables. It goes without saying that any air leak after the MAF will cause the mixture to run lean due to the added air that was not metered, and thus the lack of fuel to maintain the proper mixture.

I would agree that you either have a bad MAF or an air leak.

Upon the completion of the installation on said modifications to my vehicle, there was a vacuum leak that in which idled my vehicle between 2-3K RPM's. I did not drive the vehicle until they went back in and found the leak. After that, the rest was history and was swell.

/e No CEL's for my vehicle.

The whining noise you hear might be the free-wheel on the alternator pulley if your car is equipped with one. Mine made a squealing noise that was very noticeable with the engine cover off. Replaced it and it stopped.

the idle is normal. I just hear the engine not running smoothly. I cant find a leak anywhere. Im gonna run the diagnostic this weekend and post the codes.
