my buddy's 03 suburban has had a low idle lately, so much that you have to hold the brake and tap the gas to keep it running during stops. The check engine light threw 3 codes: PO101, PO171 and PO174.

At the local auto shop where the code was scanned they temporarily put in a new MAF (since that's the PO101 code), but it didn't solve the low idle. The weird part is that when they removed the intake, it ran fine, but when they added the new MAF it immediatley started to bog down.

Does anyone have any insight as to what might cause this? I thought we could replace the MAF and that would solve the problem.

Thanks!

Check your pre-cat O2 sensors, they are usually what cause those codes, especially the rough idle.
