holy crap what a difference. sold the thunderbird to a friend in texas and now i proudly own a 94 mercury cougar with the 4.6 it only has 113,000 on it.

i've got a few questions:
next to the tb, there is this "electrical" noise. sounds like a power box of some sort.

also, the lights dim alot at idle. could this be a voltage regulator issue (if equipped)

i don't know a whole lot about these cars but i am mechanically inclined.

ill upload some pics in a second.
