99 SLE acting up AGAIN
What'* going on everyone. It'* been a while since I've been around. All has been well with my 99 SLE up until recently. The other day I was driving with no problems. I had the radio up high and the windows down. I finally got to my destination and was looking for a spot. When I turned a corner, the car starting dinging and the "check gages" like popped up. At the same time, my lights shut off and my radio completely shut off and came back on. The voltage meter dropped to about 5 or 6 volts. Since then, she'* done it about 6 or 7 times. It happened about an hour ago as well. I was idling in park with the headlights off and the interior lights on. After a minute or two, the interior lights flickered like crazy and the radio cut off and came back on. Then I noticed my gauges going haywire. I know my battery is almost dead. It'* a Diehard from 2007...I know. Lol. I had just the accessories on about 2 months ago for about 4 minutes and she wouldn't start back up. That'* going to be taken care of soon. But back to the topic at hand. Is there anything anyone can tell me? It happens too frequently now. It even happens when I'm driving at highway speeds. It'* starting to scare me. Also when it happens and I'm braking, the speedo bounces up and down whilst gradually going down. It'* absolutely nuts. I don't know what it could possibly be.
Also, my old problem that I had with her is still around. I still can't figure it out.
Please, anyone. I need help. I can't have her die on me.

Start with the free stuff first. Check your battery cables top to bottom at the connections. REMOVE THEM from the battery. This is a common corrosion area and your symptoms are pointing at this.
If they are clean and TIGHT,
have your battery checked at a autoparts store.

1. Alternator
2. Chassis grounds
3. Battery
4. Belt tension. A slipping or worn belt, or a weak tensioner can under-drive a good alternator
5. Coil packs
6. PCV Valve- Check if fuel comes out after unplugging vacuum line for a few minutes
7. *I copied this from another thread* "My suggestion is to go back to the ground buses under each front sill plate, disassemble them, clean them with a wire brush, and reassemble with dielectric grease."
8. *Also copied from another thread* "Take the vacuum line off the fuel pressure regulator and smell the vacuum line. Do you smell gas? If so, the FPR is bad. Replace it."

You forgot to add "check battery cables" at battery. That'* should be priority 1.

Easy killer, once we get your electrical gremlin fixed, you'll be rattling windows in no time.

I'm picking up a battery tomorrow from Autozone. It'* a duralast :/. But it'* definitely better than the Diehard I have now. I'm going to check the cables while I'm at it as well.
