okay, lets figure this out again, engine indicator light came on, checked into toyota, diagnosed as code error 24 on air intake sensor. toyota replaced it, next day whilst driving home, engine cut out totally at traffic lights while engine on idle (this happened when I inserted the stereo headunit on), car wont start (but I had the headunit weeks before and it never happened, I had the car installed with Toad alarm/immobiliser as well) brought into toyota. never had this problem before only after they replaced the sensor. electrician couldn't find out the fault,they thought it could be a miswiring on the alarm or the stereo, but it wasn't. so then they strip to find 2 ECUs,we know its a stock and piggyback ECU. what if they can't find the fault from here? what else can they do? any expert advice? I just want my car fixed. bought this car in november and didn't get to enjoy it at all!
