Egrcode multiple cylinders misfire

My car has 195000 miles.
My car has an automatic transmission.

The most likely issue in this situation is with the EGR valve. Problems with the EGR system can lead to misfires. The exact problem with the EGR will need to be diagnosed with some further testing. The EGR valve itself needs to be visually inspected for obvious damages. The valve could be faulty, dirty, clogged, have a bad sensor, or have a bad connection. The valve passages can become clogged and may require a good cleaning. Upon cleaning the valve, keep an eye out for a loose electrical connection. Also keep an eye out for moisture or other debris that can cause other clogs in the system. If the problem continues after cleaning the valve and clearing the codes, you will want to look further into the electrical components, and possibly replacing the EGR valve all together.
