Well I swapped the sensor (the vertical and centered one--the RHS of the two under the alternator) and it still does it
. The one in my car was grimey and dented a bit. The one I put in looked better.
Today the engine was cold and I gave it a little rev after I started it (less than 4000 rpm) and when I put it in gear it promptly died. The engine wouldn't start again until much later today, when I had to turn the key for almost a minute. Good thing my battery was up to the challenge.
As of right now it's not giving any engine codes. Do I really have to take it to a dealership and pay $100 for them to tell me they don't know what's wrong with it?
