Well to sum things up, my ecu is throwing a million codes, such as bad secondary o2, Vehicle speed sensor malfunction, Electrical load detector circuit, etc., etc. I was just driving noramlly when my Speedometer stopped working. Then when I got onto the highway, if I let off the throttle and got back on my car would not even respond for like 10 sec. and then my car would start to accelerate. Anyone have any ideas to what might've happend?

 

check battery grounds, the frame/engine grounds.

 

check your fuse of your fuse box under the dash. one of the fuse is blown for sure.

 

Ok now my battery is dead and my car wont start. What could it be?

 

anyone?

 

did u check the battery grounds and frame grounds?

 

maybe you have a bad connection on your alternator?? i had the same problem last nite, and that seemed to fix the problem...
