3100 V6(L82) engine questions/problems???

[goozle63]

so i have a 1997 grand am GT with a 3100 V6 (L82). I havnt been driving it very long and it seem a little sluggish, and its not weighted down, its just my 140 pound self in there. How much horse power and torque do these have stock??? like if im goin 15mph and punch it straight to the floor its just a slow increase in speed, and the rpm's dont harldy even go up. It doesnt seem to have the power that a V6 should have. any suggestions? im not too smart with engines so im not sure what it is if anything, maybe timing, sludge, old air filter,transmision(automatic)? i dont know so any advice is greatly appreciated. its got 83,830 miles on it. thanks alot all

155 hp, but this is really general information, MSN Auto's will tell you how much torque and hp the car has.

you probably just need a tune up if you haven't gotten one. you should have definitely had one by now.

There is a lot you can do performance wise, some easy, some cheap, and some that is very in depth:) As for getting your engine to its peak as it comes from the factory, I would start with the GM top engine cleaner in the gas tank, and ran through a vacuum line to clean out the manifolds. Regular AC Delco plugs (iridium if you just want to spend more money on plugs). Good wires, any new, or mangecor if you want to spend the money on a set that will last forever and work flawless. New paper air filter works the best as a filter, or any K&N type drop in. MPRacing.org may have a cold air intake if you want to upgrade for better than stock performance. High flow cat if your stock cat is plugged up. This will hurt your mileage and performance so let us know how your milage has been.

Thats the basic stuff I think.

It is a 10 year old engine, and probably only has 140 or so left in it by now.... How much do you want out of it? lol

That is the saddest thing I ever heard.

Mine ia 13 years old but it only has 50k miles...I hope it didn't dip that far down.

probably not. id depends a lot on how many miles is on the engine

last time on the dyno my 99' 3100 was still putting out a bit more power than stock with well over 100k on the motor and trans... only mods were a CAI and very very mild PCM work...
