........Still having problemo with rough idle

[amit 0]

Some of you might remember my post, when i stupidly let the charcoal cannister catch fire by letting it hang above the exhaust. Obviously the charcoal cannister, was fraggled, the brake servo pipe was fraggled and the air intake pipe had melted. NOW.......I have replaced the charcoal cannister with a new one- re situated it to the other side of the engine. I replaced the brake servo pipe, and fitted a ABD racing air intake pipe. I still get this annoying "bump" "bump" feel when the car idles. To me its obvious cos i drive the car all the time, passengers havent noticed anythig, but i know its there. Apart from the above items, ive also fitted magnecor KV85 leads. When i replaced the b/servo pipe, i noticed two small black nozzles off it. One has a thin tube running of it and other one was giving off air. Also i ve noticed if i disconnect the MAF sensor while the engine idles, i noticed the engine will rev up & down slightly. While ive fitted these parts, i was wondering if ive over looked some thing?? Any help appreciated.
