Earlier today, i acclerated hard up to the red line in 4th gear, but just before the rev limiter came on, I noticed the emissions control system light (the one that looks like an engine) started flashing. I slowed down, but the light continued to flash, the car appeared to drive normally, accelerating normally , and generally pulling fine. The light stayed flashing until I switched the ignition off and back on again, since then it hasnt reappeared, even if I accelerate hard in each gear. I'm presuming its nothing, but just wondered if anyone knows what causes the light to start flashing. The manual just says:- "if the warning lamp flashes drive on at reduced speed and seek professional help in order to avoid damage to the catalytic converter" Any ideas?
