I haven't tried the re-learn yet, but wondering if this alone should resolve this issue? Are there any other symptoms that would indicate the need to rerprogram? The MAF is also used (bought from a guy here) that said all was working ok.
Thanks

Just wanted to give you a heads up, the idle re-learn is a different procedure from ECU reprogramming. I replaced my MAF and the replacement OEM MAF I received had a note in the box stating that the ECU should be updated. I had it updated 18 months prior to replacing MAF and therefore I believe I had the latest software available and didn't have any problems. There have been many discussions where others have not had updates and have and have not had problems. Do a search for those discussions.
I suggest doing the idle re-learn and see how things turn out. You may want to disconnect the battery for 12 hours prior to doing the re-learn. This will clear the ECU.
