Alright we switched the ecu and the car starts now, its running okay now but the car isn't running perfectly, i took it for a drive and the car died on me after i got around the block. Boost gauge is dead now andthere is no check engine light but could it be bad o2 sensors? At idle the rpms go up then down then up and down etc etc...
