Loose Battery Cable....Maybe?

[zZsKyZz]

I was on my way out of school today and I go to get in the 'Stang. I turn the key expecting it to start and it did, for 3 seconds. It revved up to 6k then dropped and everything died out. Then the power to my radio started clicking and it was flashing. My voltometer read <8volts and nothing was working. I popped my hood and wiggled my battery cable a little and then it started back up and I had a normal 12volts before I started it, 14ish when running. Then I took it out of park into reverse and it stalled out. I went back to play with the cables a little more then it started, I let it idle for a minute or two then left. It was fine the whole ride home and for some reason it felt like it was pulling like crazy. It idled at it's normal 800ish and ran fine.

Any ideas besides a bad cable? Maybe it's just cold out?!

I would clean and tighten the cables since that apparently was part of your issue.

However, I would want to find out why the car revved to 6K for no reason - that could be extremely DANGEROUS if it were to occur while on the road way in your automatic.

Good luck.

Well the AODE was just rebuilt about 8k ago. I don't think it's that.. My other thought is, could it be a MAF sensor or such to make it rev so high?

check your iac. is the "check engine" light on?

The IAC should not be capable of revving the motor that high from idle. I would want to ensure the throttle cable/linkage is not able to hang up, etc.

I wasnt suggesting that it was an issue with your trans. But if it decided to stick while you are in drive, IMHO it takes longer to think to push the button and pop it into neutral than it would to depress a clutch pedal.

Runaway cars are kinda sucky.

Good luck.

Well, the reason for the loss of power IS the dirty battery cable/terminal/etc... I just replaced it about 3 months ago and now it's dark black.. looks like carbon...I'm guessing it's from the winter. I'm going to use some major contact cleaner on it and a brass brush.. ya know..and that **** to clean the terminal.. etc... baking soda..that's it.

Ahh, guess it's time to get the 'stang ready for summer .. Meaning new ****..

hmm, last week i unplugged my iac (idler pully broke, belt came off, had to replace it) and ever since it'll revv up to about 1500 on a cold start for about 30 seconds, then drop down to about 800 (normal). i havn't pulled the codes yet (not a single advance around here has an obd-1, gonna have to go to autozone ), but will try and do asap.

Paul, that is normal IMHO. I have my hot idle set at ~800 RPM, and the cold idle hits 1500 RPM for a few seconds at start up. Then it settles to 1000, then 900 within 20 seconds or so.

Individual settings will vary with idle set screw and idle bleed settings and mods.

I was earlier referring to Sky having hit 6000 RPM - that aint normal! And the IAC is not able to do that.
