I recently purchased a used Altima from a private seller and the issues I'm having!!! Ok here are a few things going on.... The engine randomly shuts off while both idling and actually driving (shut off going 55mph yesterday!). My radio when you turn it on sounds like someone tapping a microphone and that is all it does. Replaced the factory amp with exact one and now my interior lights (blinkers, lcd dash that has mpg/dte/trip a/b doesn't work) and chimes don't work. I have to now press the shift lock button to put the car in park that just happened today. The engine light came on and has some weird message that the people at the local shop didnt even know what it was. We have changed out so many parts in this car already I seriously don't know what else can go wrong on it! Checked all the fuses on dash and under the hood all are in 100% working order. Can anyone help me!? I have a 2 month old son that rides in this car.
