JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: it originally was misfiring on one cylinder. i replaced plugs, coil/boot and fuel injector on cylider 4
JA: How many miles are on the car? Is it a steady misfire? Or random?
Customer: 225K. it was a steady misfire. diagnostics said cyl 4 misfire
JA: Anything else you think the mechanic should know?
Customer: i pulled boot coil and plug to check for spark, only one had any

Hello. Welcome to Just Answer. Please allow me to assist you. This car's coil system shares a common ground across the coils. If one coil is bad, it can cause the next coil to fail, and cause a misfire, even though the faulty coil does not exhibit a misfire. The recommendation I have for you on this request would be to replace all of the coils on thsi car with genuine Toyota replacement parts. Non-Toyota coils can cause the problem to reoccur, as they do not have the adequate ground isolation (which is most likely causing the problem in the first place).
