Did you ever notice at night when your at a stop light and its idling rough, your lights will dim as if you turned on the AC, rolled down the window, and plugged in your Cell Phone all at the same time. What my gut feeling is that it is our alternator. The ones they used must be from the 230, or something because it dips way to low. I want to know what is drawing that many amps to cause it to seem like it just might stall. I read somewhere that they installed 90 Amp alternators, instead of the required 120 Amp.
