speaking of that my car idles REAALLL bad!! and i got a coil pack from a friend that had wrecked his car that was a good running mustang my idle got better but only for like a week...

 

yea man that sounds like the alternator isnt conducting any amps if that isnt your problem then mabey you have a loose ground some place. and the gauges and all the electrical stuff is just being reset be the ecc/ecu

 

i was thinking of just taking it to a mechanic and see what they see.. i mean i really dont wanna pay labor lol i mean who does?

 

yea i know what you mean thats why i do all my work myself its cheaper that way, just see if the alt is bad first auto zone doesnt charge to check it and then go on from there good luck man

 

preciate all the help

 

I just wanted to say this: NEVER run an engine with the positive battery cable disconnected, it 'full fields' the alternator, and will damage it quickly.

 

HUH??????????????

 

Really??? everyone always tells me to test it by doing that.. maybe my alterator is bad then

 

Just removing it for a short period wont do any damage. But its always better to remove the Negative terminal. I am betting your alternator is bad, unless you have a ignition problem causing you idle to dump to very low levels. That will also cause your lights to dim, and other things. Get that alternator tested then go from there.

 

ok man, i got a new battery and my alternator checked they are both good.. what now.. maybe the wiring harness or ecu??..
