2010 Yaris hatchback , 100,000 miles , automatic transmission.
Issue #1 : Not all the time ,but when I stop at stop lights / signs , the engine shakes as if it's going too stall out. Out on the road it's fine. I'm going to clean the MAF sensor. The battery is 18 months old.
Issue #2 : Speaking of the battery. Over the last several months I've noticed acidic buildup on the positive terminal / post etc. I've used baking soda and water to clean away the crud. BUT , I can't get the positive terminal / clamp to come off of the post. I've loosened the clamp nut and the other fasteners at the rear of the post but it won't budge! , what the heck?. I'm not a noob per se regarding general maintenance. If I place any more muscle on this clamp I'm concerned I'll break something. And yes , the negative clamp has been removed from its post. TIA.
