Did this start out of the blue or after something was worked on under the hood?

Default It was like it when I purchased the car. Still have cold idle issue+ when coating.

When I purchased this car it had this issue. I thought it was the IAC or TPS. I changed both and reset idle and also adjusted volts on TPS to below 1 volt. I still am having cold idle issues. When my tank was half empty yesterday I added 87 octane hoping it would help it with idling and also with jerking when de-accelerating. No such luck. Will adjust the throttle body set screw and fill entire tank with 87 octane when near empty. Hopefully this will help, if not I will put her in the shop as soon as it is in the budget.

Could even be something as simple as the "ACT" sensor







They are usually pretty cheap at the local parts store and very easy to change.
