just bought 2001 toyota sequoia 218k miles did spark plug change and saw residual coolant droplets on cylinder 7 spark plug tube seal, oil looks good, doesnt overheat, has cylinder 7 and cylinder 5 misfire (adjacent cylinders), ignition coils are tested good, no external leaks anywhere, i know a head gasket isnt common for these or cracked head.... also throwing codes for 3 o2 sensors and catalytic converter? any suggestions get this thing to stop misfiring
