Hi, I drive the 23i (manual). The car idles aright but every now and then when I come to a stop the car nearly stalls under 500rpm and then bounces back to 700-800rpm engine hot or cold, as of recent it also seems a bit down on power although it's been a while since I last hooned it. Told my mechanic to check the maf sensor but he said it looked alright, he reckoned could be the fuel filter, but apparently these cars came with lifetime fuel filter. Car has 62k miles. Any help or pointers much appreciated.
