Help with dead battery/check engine light

[redturbo66]

Okay, here's whats going on..........last night I came home and parked my car. There were no problems at that time. This morning I went out to my car to go somewhere and the battery was dead. No prob...went and got another battery. Just put it in about 45 minutes ago and now the car has a "service engine soon" light on and the idle sucks! The engine is sputtering and making the whole car shake.
I need help with this quick! Please!!

prob nobody responding because of the title of your thread......should'nt be talking like that bro' it's only a car....., anyway.....i think that the problems are probably unrelated unless the alternator in the car is junk, that's a possibility.....

Take the car to autozone and let them test the alt and battery (its free AFAIK), and see what they say. Its probably the alt causing the battery problem (unless you have something that is using power when the car is off). As for the idle problem, how old are your plugs and wires? I'd try replacing the plugs (only use NGK BPR6ES plugs) and see how that works.

My car is now fixed. I drove it to autozone to read out the codes on my ecu. P0201...injector circuit malfunction cylinder 1. I unplugged the injector, wiggled it around a bit and plugged it back in.....started up the car and then the problem was gone. So it had nothing to do with the battery.. I just have bad luck with cars. Thanks for your help guys.
