1992 Mitsubishi eclipse odd power surges?

I have a 1992 Mitsubishi eclipse that has odd power surges.  It is sluggish about 90% of the time and then it has random boosts where I leave about 4 yards of rubber on the road.  I was wondering if anybody has any ideas on how to fix this.  i intend to give thew car to my girlfriend but i have a bit more experience on junky cars than she dose and i don't want her spinning here tires in the snow due to the boosts in power.

Sounds like it is dangerous as is and a real mechanic should take a look at it.

I am no stranger to engines the problem is that i have had 2 injected cars and never had fuel system problems with the other one so all of my experience has been with carbs
Still, the description of the symptom is dangerous since it's random and apparently full power is applied. It's irresponsible to drive this car until it's fixed and fixed right. This is not a problem to tinker with.

Sounds like clogged or bad fuel injectors, fuel pump, or something else in the fuel system. You can try a bottle of some fuel injector cleaner, STP makes some I think. If it improves then you know where the problem is, if not you can't rule it out though.
I wouldn't be driving this car in the snow, or probably at all, since a power surge at the wrong time could easily end with you, your girlfriend, or someone else dead.

no kidding when you are on the highway and suddenly accelerate you could be driving straight to where somebody is merging
