Alright, so I went to change the map on my 2003 WRX today to an economy map. I knew something was up when the key fob wouldn't work, and I had to use the key itself to unlock the door. I got in the car, put the key in the ignition, and noticed that not even the gauges worked. It was completely dead, no windshield wipers, cd player, nothing. I looked around to see if I had left something on, and sure enough, I had left the map/reading lights on. The bad news is that the last time that I had driven the car was probably a couple weeks ago. So I jump-started the Subaru with my Xterra. As soon as I had the cables hooked up, all the accessories worked. I let it charge for a couple minutes without starting the Subaru. I started the Subaru and it idled fine for about 30 seconds, then RPMs would fluctuate and it would idle very rough. I cut the engine off and let it charge (assuming that the battery didn't have enough of a charge yet) for another 8 minutes or so. I got back in and started the car again, and it did the same thing, idled rough.
I figured that the rough idle might have been caused from the fact that my Accessport reflash would have been wiped out since the battery died, and since I have aftermarket turbo/injectors. I unplugged the cables and the car would not start. I still seemed to have full accessory power, windshield wipers/cd player and what not.
So, do you think I may need to let it charge for a really long time off of my Xterra before it will be able to idle okay?
What is causing the rough idling? I installed my AP reflash right after I installed my 565cc injectors, I cannot remember if my car idled rough before I had the reflash or not. I know that some tunes can make your car idle rough, but since my ecu had been wiped out, wouldn't that mean that I am operating on stock ECU parameters?
Is there any hope for this battery? Or do I have to pony up for a new one?
Thanks in advance.
