Losing power
 
Not sure what is going on, but I know what's NOT wrong.
Been having electrical issues for months, have made many changes, but still no luck. Things improve for a while but still haen't gotten to the main problem.
First off, the basic problem is I am losing power while the car is idling. While sitting at stop lights, you can watch the battery guage just bounce back and forth between the white lines for 8 and 12 or 14 or wahtever it is. Sometimes it will even stall out. This usually happens right after starting the car and say backing out of a parking spot or something. It will restart right away (so far) but then the check engine light will come on. It will drive fine for a while then the problem returns.
Second, here's all I have done so far to correct this.
New plugs and wires.
New battery
New coil, other two are fine
Alternator is less than 2 years old.
I have have had the alternator and battery tested several times to make sure they are fine, and they are ok. I just had this done the other day and with the car off the battery tested at 12.8 volts or so. SO, I know the battery is good and the alternator works or the battery would have died by now.
I know I am gonna need to get it put on a computer and tested, but the garage I called wanted $55. Ouch!
I don't have any good garages around me I trust that have computers, so I am not sure whre to go.
Any suggestions?
Thanks

Do you have OBD I, 1.5 or II ?

tallbump 09-28-2006 12:02 PM

Not quite sure, I think its the OBD 2. The one that Autozone can't read for me!

Have you checked the battery cables by pulling them at both ends of all cables..cleaning..pulling the boots..looking for corrosion and reconnecting?

you are OBD 1.5

BTW..there is no code for clean and tighten cables. 8)

tallbump 09-28-2006 06:56 PM

Yeah, I was wondering what code that would be.
But, actually that was the problem. I checked the terminals. The positive was so loose I could take it out by hand. The neg was loose to butnot that bad.
Would this make the check engine light come on?

well when the PCM dosent get all the Power that is wants, it will act funny....and we all know how the 95 PCM's like to fail...

Well, I was wrong. Sorta anyway. The cables were loose. But I dorve to a store about a mile away and it seemed fine. I waited outside while my wife ran in for about 10 miutes. She came out and I went to leave and drove a few hundred feet and it stalled. It happened twice more before I got out of the parking lot. Not sure what is going on.
Any thoughts?
It does start up right away after this happens. I guess that's because the battery is good. So annoying. :evil:
