When let off gas the engine idle drops down and stalls. Ok at first when cold idle on but once warm stalls when let off gas. Problem started after removed battery terminals to clean with baking soda.

Have the IAC and throttle body cleaned, it should solve the problem.

Thanks, cleaned the throttle body (used throttle body cleaner) and the sensor at top of air filter cover (used MAF cleaner). The idle is back to normal. I did not see how to access IAC, hopefully the throttle body cleaning reached the IAC?

IAC is under the throttle body so while cleaning the throttle body if you had sprayed carb cleaner into the 2 lower ports, that would have at least partially cleaned the IAC. If the idle is normal without much differenece in idling when A/C is turned on or off, then there is nothing to worry about.
