do u keep a wad of keys with you car's? the weight of a lot of keys and keychains really ****s up your ignitionover time. you wouldnt thinkso, but try holding just the teeth portion of you keys between your fingers (just like they go in the ignition), then try holding just one key this way, its quite adifference. i keep my keyringsfor my cars separate with only one or two keys on it.

there is also a relay that tells your transmissoin that your foot is on the brake. i had a fuse go out onmy probe once which prevented me from reoving it from park.
