I had my battery replaced at Autozone yesterday. The car would not start the day before but after it was jumped it ran as normal. I brought teh car to Autozone as a precaution because I was traveling out of town. After they check the battery they determined that it needed to be replaced. However, once the battery aas replaced my car has not run correctly. It idles very low. If I go under 15 mph with the ac on the car completely kills.

check fuel pressure

Sounds like you have a bad Solenoid

Battery is too low to turn the engine over. Get it jumped and drive it to AutoZone. They will run a free diagnostic and tell you whether it's the battery or the alternator.

You were told the battery and alternator was good? how did they check your alternator? did they perform a load check on the battery? you should check the battery out yourself with a cheap digital meter...it should read at least 12.5v..if not the alternator is not charging your cars battery that is why a jump keeps it going for about a day and then your battery will drain and it wont start again until you get another jump; or your serpentine belt is worn out and slipping. Do the windows fog up in cold weather only?...because that would be normal with you sitting in your car for awhile with a dirty inside windshield and trying to start the car for long time..it just could be a coincidence. The only reason your car started that time in haste was because it sat overnight and it gave the battery a chance to charge up somewhat and it barely had enough juice to turn it over. have AAA or someone jump start you, then take a voltage reading right as it starts and you should see the voltage rise to about 14.5v then stabilize slowly down to 13v or>. this voltage is being properly regulated!

Is you battery going dead? How old is the battery? After 4-5 years a battery is bad and needs to be replaced.

It sounds like you didn't replace the alternator?

Do you get a click when you try to start and it wont start?

Also check the grounds on the starter they could have corroded and this would cause an non-normal starting pattern. To chech these locate them, usually close to that starter and screwed into the frame of the vehicle. Unscrew them and take a wire brush and clean them very good making sure to expose bare metal. Do the same to the frame where it is screwed into.

Make sure to unhook you battery before doing anything!

Reply with the answer to the questions and we can go from there.

Make sure the battery and alternator is working. Get battery and alternator checked. It did not jump timing. Autozone will do it free and Walmart will check your battery. Lets try this and get back with me

Ignition control Module out again? Over energized?

ground missing, had same problem ran ground from battery to frame

recharge battery check to see battery cables are clean and tight when starts have your alternator check for output

i ran into EXACTLY the same problem on an 86. i kept forkin' around and finally went direct to the starter and bingo it started. to this day it is still working and never happened again. i have absolutely no idea why. by the way--that was almost 2 years ago. might also be corrosion between the battery cable @ the starter, and the wires that go to the waring harness.
