Lexus ES 300 Cylinder misfire
About two weeks ago, the CEL came ON and car start to shake when stopping or slowing down. I did the diagnostic testing and it shows cylinder 2,4,6 misfire along with a code p1150. I bought three ignition coil and replaced them, i also checked the spark plugs and they all look fine. After replacing the ignition coil, I cleared the CEL code and did a test drive for about two miles. The car started to shake again when stopping with the CEL flashing.
I also noticed that the catalytic converter glowing red, I suspected this could be due to the misfire, unburned fuel getting in there. Please help as to what I need to check next. Do i need to change the catalytic converter? Also in the past couple of years, I replaced the ignition coil about 3 times. Could it be something else causing the cylinder to misfire? Help please, I would really appreciate it.
