P0202 code is that true. i had my battery checked. it said good but needs charging and it read 500 and i guess it should read 550. i have noticed little things going in with the car such as the alarm system doesn't sounf as loud, the horn you can hardly hear and the power windows are very slow to go up so i am thinking it's the battery, also car doesnt stall and seems to run okay unless i go to accelerate at about 30 mph and then it loses power

It could do the 300, but the 202 is in injector system failure on #2 injector, bad injector, bad wiring, or bad main computer circuit that fires the injector. Good luck
