idle problem

91redgt · 11-23-2002, 02:54 PM

I got a 91 Gt and whenever I have it on my amp gauge starts going down. If I start to drive it goes to normal but if I put the A/C on and radio it starts to go down again. What could this be? This is my first stang so I don't know much about them. Any help would be great.

Let me guess you have an electric fan dont you?? Mine did the same thing when I put my electric fan on my 88. The stock alternater sucks. Upgrade to a 130 amp alternater and your problems will be solved.

Later,

how low does the guage go? it coule be a 'ford wiring" thing... some guages go down (like mine and i have a 130 amp alt ).

take care,
adam
