My car was driving fine then all of a sudden it started losing power Lil by Lil and then it would stay on but had no power and then I would let it set till the next day and would it would start up and drive for a few blocks and then start losing power all over again and then die out. Then I had a diagnostic test ran on it and these are the codes p0401, p1603, p1500, p0403 can you give me some suggestions on maybe where should I start

Code definitions are as follows;

P0401 Exhaust Gas Re circulation Insufficient Flow Detected
P0403 Exhaust Gas Re circulation Solenoid Malfunction
P1500 Generator Terminal Circuit Malfunction
P1603 Battery Backup Line Malfunction

You have a problem with the emissions system. The solenoid needs replacement and that is probably the best place to start. It sounds like there are several problems with the car that are electrical. This can be hard to track down the source of the problem even if you have the trouble code. Have the electrical problems checked after you get the solenoid fixed. I also suggest going through the walk through diagnostic for loss of power as it will cover other most likely problems that cause loss of power. These may not come up in trouble codes. Just use the link below to get to the diagnostic;
