Computer problem?

Hey guys,

I got 1987 325 vert with an engine that has been replaced.
Here's my question:
Whenever I drive the car, after about 5-10 min on a highway, i feel a sudden loss of power that lasts about .2 of a second (just enough to feel it) and my check flashes (I always have a check for washer fluid as my cable is cut).
I am under impression that all the warning lights have been turned off so who knows what's wrong there, but it did pass CA smog and drives fine.

Anywho, i am afraid to be stuck on a highway because I lost power.
Well, yesterday, when I drove it again, the lights inside the car were flickering and when I finally parked it, the headlights flickered heavily and went back to normal.

Any ideas?

As a couple of guesses, loose connections or erratic relays?

how can i check that?
im a maintenance n00b

Start with the relays; they're in a box which makes testing kinda easy.

iggy,

try to find out if the motor that was replaced was the correct motor for that make/model/year.

also, like tommy said, check the fuses/relays, then go from there to the alternator. The flickering lights is usually an indicator of a bad alternator or incorrect alternator.

Glad to have you back.
