Hi, I'm new to the forum. I've owned my IS200 for 5 years and been really pleased with its reliability.
Just recently, the engine light started flashing occasionally. I borrowed a fault code reader and this was shown as:
- random misfire
- misfire cylinder 1.
Spark plugs were replaced not long ago - so I replaced the coil pack on cylinder 1 too.
The problem came back... It seems to happen more in warm weather - and more when driving at lower speeds or stopping part way through a journey. Could this be because of a heat soak effect?
I borrowed the fault code reader again:
- random misfire
- misfire cylinder 4
- misfire cylinder 1 (pending)
- too lean bank 1 (pending)
Coincidence that another coil pack has gone? Or some other problem like a catalyst or a sensor?
TIA
Nick.
