Hey, guys. I have a 02 IS300 that has been giving me problems since I bought it. It has 240k miles. A few months back, I lost a coil pack (cyl 2). It destroyed the plug at the same time, so they were both replaced. Ran fine for a while, but then started misfiring again. Replaced all plugs (denso iridium power), coils, wires (NGK), and replaced all three connectors (soldered, not crimped). Still misfiring on #2 and #6, but only at idle. Runs smooth over 1500 rpms. If anyone has any insight, it would be much appreciated.
