Okay... Im going to post all symptoms my car is having.. and hopefully you guys can help me decide if theyre all connected, or what needs to be done..
1976 Pontiac Firebird Espirit, 4.1L Inline-6, 250 c.i., auto
Certain times, only in the mornings (which are NOT cold here in FLorida, especially this year) I have a pretty loud groan.. HUMMMM... coming from under the hood.. passenger side near firewall... pic of that area here...
Pic under the hood (flash makes it look way dirty, lol)
Now, when I was on a 3.5 hour trip the other day... I noticed my headlights were dimming real bad, along w/interior lights when braking while stopped in a traffic jam... had much time to play with it, realizing lights in/out only dim a FRACTION as much when I'm in nuetral.. vs being in drive, where they dim considerably.
Well, I decided to pull my neg terminal, ran it for 5 minutes, no problems whatsoever, so i ruled out the alt...
Now, when driving around town, at lights, I notice, only when in drive, a very very light, barely noticeable, growling type of hum coming from under the hood, from possibly the same area.
Now, before this trip I never really noticed a problem before...
The next morning... I drive up to Taco Bell (maybe 3/4 mile), when going to drive away from the window, I have the shifter in drive, but it's in neutral, after slightly tapping the gas it eases into gear just like normal, not slamming in as if it has bad bands..
This week, back home, at work, I went to back out from work, had it in reverse, same situation, slight gas, maybe 250 rpms over idle... EASES right into gear....
Checked fluids, all clean, new, and totally full, this car is immaculate.
I feel I might have bad grounds, which could lead to the lights.. but what about the rest?
Thanks in advance, guys! And here's the ride we're trying to fix!
