Looking for some advise on a DTC code my 03 cobra is throwing. I have had the car for three months now with 24k on the clock. I am getting a p1112, and p1000. By means of a sct xcal2. The DTC will clear on its own, and i wont see it for a week or two, and then its back. Regardless of check engine light on or not it will die at a low idle only when coming to a slow stop. This only happens once or twice every 200 miles or so. I have inspected the air intake temp sensor (not like that will tell me anything anyhow), and will replace it this week. My concern is it is unusual for a low mileage car (at least in my experience) to develop a faulty sensor. Maybe i have a bigger problem that is tied to the obd 2. The previous owner has went with a 3in pulley, idlers, and a mail order tune. There is no way now for me to validate what tune if any has been flashed to the obd. My xcal is still vin locked to my lightning. I have not had the car on a dyno as of yet for a proper tune because of that. Any ideas, or if someone has had the same problem any advise would be appreciated. Sorry for any stupidity in the above, but the last time I really had to trouble shoot engine management was on my old fox, and a timing light and some hardware always got the job done then. Thanks.
