Red Light on Dash

[Onlydamo2]

Hi, Just wondering if any one can help. I have a 1995 K11 1.0 march. Had a problem with idleing recently and the car would cut out when slowing in traffic also had a red light come on the dash with a symbol that looks like an exhaust with 3 lines rising from itthis is beside the eml . did a bit of tinkering around to find the rotar arm needed changing, this fixed the idle issue but the light has not gone off and the car seems to be low in power. Has anyone any ideas. any help great welcome
