Hello everyone and thanks for any help. This is my first post on this site so I hope I get everything right.
I have a '94 Chevy Caprice Classic. It has somewhere around 200,000 miles on it. The problem I'm having is that my battery gauge fluctuates when idling in drive. It takes a minute sitting there and then it drops frantically. If I put it in park as soon as I see it, it picks itself back up no problems. It also has a tendency to do this more if it is raining bad. I don't know if the car is struggling or if me running the lights and defrost are affecting it. It always almost shuts off in a storm.
Now forgive my ignorance but this is what has been replaced and/or checked in the past year. All these were to fix this problem.
The Distributor, Cap, Rotor, Module, and water pump gasket.
The Temp. coolant sensor. A new serpentine belt was put on. Both battery cables and a battery cable terminal?. The ignition control module was replaced. The battery and alternator were also tested. The scanner also cleared as this point, saying no problems were found. This endeavor cost me about $1000.
Of course the problem returned and I have since had 3 more distributors put on and a new water pump. Also a radiator hose replaced. The oil has been changed, new tires put on, all fluids have been checked, and cleared again as if it was fixed. These endeavors are pushing my total close to $1500.
My car is still not working properly and I really don't have the money to keep throwing into guesses. It's also a little nerve racking to keep breaking down at night, alone. If anyone could suggest an area that may be the problem I would greatly appreciate it. I don't have much mechanical knowledge but I'm sure I can figure out what y'all are saying. Thank you to anyone who can help. Also, if I did anything wrong or left anything out in my post, please let me know so I can correct it.
