Reset computer: Engine idles fine. First few trips - and this does involve the engine getting up to temp, stopping and cooling down and then starting back up again - the engine idles fine and throws no codes. Then I'll start it up and it'll idle rough. When it does that, I check and it's now throwing code 52. It doesn't take weeks, just me driving it about three round trips to work, or so.
But you're right, it doesn't make sense that I can drive a handful of trips and it idles fine (and there's no gas smell). And then boom, idles rough, gives 52, and I smell gas when I get out of the Jeep.
