Hey guys. I drive a 2005 Croma 2.2 auto and I've been having a small problem. The car had a 646 battery when I bought it and the seller told me the battery has to be replaced. In the morning the car would start perfectly but the engine light will flash, the asr would go off and the car would only drive in 3rd gear. I prosume that it goes into limp mode. After driving the car for a while at restart the car will be fine. Some people told me it could be the battery. When I checked, the manual suggests a 90Ah battery, so I bought the closest I could find which was a 85Ah, however the car still goes to limp. Can anyone tell me what could be causing this...?
