All I did was change the battery, its been idleing rough and stalling when you give it gas. It is a 5 speed. Changed tps and does not help. So I need help. Was running great before changing battery. Thankyou

The Engine Computer lost its memory and has to relearn "minimum throttle" before it will know when it must be in control of idle speed. It also might not give you the normal "idle flare-up" to 1500 rpm when you start the engine. To meet the conditions for the relearn to take place, drive at highway speed with the engine warmed up, then coast for at least seven seconds without touching the brake or gas pedals.
