Does the engine seem to be misfiring or not running properly?

What do u mean by misfire?
Automotive Expert
As in is the engine running rough/not smooth.

I just popped the hood of the car. The battery is covered in blue dustWhere the battery for the car connects

Ok. This sounds very much like you have a malfunctioning coil pack. The coil pack is what causes the [spark plug](/topics-spark-plug-toyota/) to spark. If one coil is malfunctioning, the engine is only running on 3 of the 4 cylinders. Now, to determine which of the coil packs are faulty, you need to get a scan of the car's computer. The scan will dictate whichj coil pack needs to be replaced. The blue dust is battery acid leaking out of the battery. This would need to be cleaned off and the battery terminals cleaned also. Most auto parts stores perform scans; they can assist you with which coil needs replaced.

Does a coil cost alot?
Automotive Expert
Genuine Toyota coil packs (recommended) are about 125 dollars.

Where would I go to have the car diagnosedOkIs there something needed to clean it off?
Automotive Expert
Any good repair facility, or, the best is a Toyota dealer service department.

I am at auto zone and hey said hey don't carry the machine to diagnosis because of covid-19
Automotive Expert
Auto parts stores sell a spray on product specifically designed to clean battery corrosion (the blue dust).

OkayThe car is undrivable because of this issue?
Automotive Expert
That is sad that they cannot do the scan. You next stop would be an auto repair facility then. I would recommend against driving it long distances. Do you have any other questions for me on this request? Thanks!

Thank you for your help!!
Automotive Expert
You are very welcome. Have a great day.

Still not sure what you need?

Have a certified mobile mechanic diagnose what's wrong with your car, at your home or office.
