motor shake and no dash lights

[superdutyscaler]

been trying to figure out whats going on with my sisters 08 focus. Its a 4 banger that has 58k on it and ill start by what happened...
about six months ago she was going home and hit this VERY bad railroad track and the car actually stalled, she called my dad and he called me and i went to the street where she was the car was completely dead, so i removed the battery cables and rehooked them and it started and ran fine. A few days later she said the car shakes in idle or park and sometimes now it shakes very bad when dving down the street. Also a random times the dash goes out no gauges at all and then comes back on and its fine for a few days and then it quits again from a few seconds to almost a half hour one day. Ive been using my scanner evertime it does this but the car throws no codes so either something is loose from her hitting the railroad track or theres a short in the wire harness???

I believe I'm having a similar problem in terms of the dash lights going off and on erratically. Any luck?? I tried the connector to the switch ( headlight switch ) but no luck...
Anyone have a bead on this issue??

yes, finally took it to the dealer and the PCM was fried! They did a complete test on the car and they finally said that it problly was just a "badone" and it just went. $800 bucks for new PCM and testing car has been good for over a month now
