glad you have got the radio sorted - as i said kids love putting things in cigar lighters (little angels),
Next problem... my other car is a 2001 seicento. think this might be just sensor problems. 1. abs seems to be on all the time (that juddering) took abs fuse out and brakes are ok except abs light and handbrake light on all the time. 2. when idling revs go up and down as if pressing throttle - from idle to about 1500 revs and back again. Any ideas. Thanks again
(1) possibly sensor failed but more likely dirt/dust/grease( from split c.v boot)/debris on a wheel sensor/induction ring - check, dust out with airline or hoover or clean with paintbrush or brake cleaner spray
(2) could be dirt or soot on mass airflow sensor - clean with brake cleaner spray or could be a split air pipe - check ducting from m.a.s to inlet manifold and all air hoses to/from inlet manifold, possibly m.a.s, air temp sensor etc.
it would probably be worth getting a garage or mobile auto-electrician to scan for fault code errors if you have checked the obvious things above and the faults persist - good luck - Jon
