Hi guys, I am new here. I have a 2004 Lexus ES330. I am the second owner and have owned it since 2012. It is currently at 64000 miles and I am based on Hawaii.
For the past few days, the engine has been running quite rough and shaking as well. When the check engine light first came on, it was blinking for a while and then remained solid. The codes are P0303 and P0353.
I took it to a local mechanic and he said that there are two cylinders misfiring. He said there were oil leakage inside the valves and quoted me $1200 to fix it as well as the ignition coil. He said that the cylinders are underneath the engine.
I want to ask is this reasonable or is he ripping me off?
