That could be an oxygen censor going out or a fuel injector problem . the true way to fix this problem is to take it to a mechanic .

How to Boost Your Car's Horsepower?


There are no easy ways to do this. There are some pretty questionable claims about things that you can add. Most of them are intake devices like cold air intakes etc. They are all scams. The only true way is add very expensive parts like the cam being changed or a supercharger on the intake. Not worth it unless you race.

2004 pontiac grand prix supercharger make a whining noise power streering is full


Hello
All superchargers get pretty noisy make sure that the supercharger is full small allen head inspection plug next to the supercharger pully, the next thing to do would be to remove the supercharger belt and start it and see if the whinning goes away if it does then it is the supercharger making the noise. I wouldn't rule out any of the other pulleys making the noise remove the other belt and make sure that all of the other pulleys spin freely and make no noise when you spin them by hand.
Good luck

The chattering sounds like some thing loose,like a mounting bracket. or the shafts end play is excessive,there can be bearing failure at high mileage in the supercharger, The bearings are lubed by the engine oil while running check for oil leaks in the line to the supercharger.

Im tryin to take a supercharger off a 1998 park ave 3.8L i took the all the bolts out but its not seeming to move can u save me


there is a large gasket under the entire thing. Are you sure that it just isn't stuck on there? I believe I did a little prying to pop mine off my Regal. There weren't any hidden bolts, nothing out of the ordinary

1998 Pontiac Grand Prix GTP Supercharger coupler


The rattle you are/were hearing is typical on the Eaton blowers. After they get some miles on them, the coupler wears out and the holes become ob-longed or out of round which causes the rattle you are hearing.
Usually at idle you can hear it very clearly.
I have changed a few, and they are pretty simple to change. Just take off the supercharger belt, then you may have to remove your alternator bracket, depends on which years, drain the supercharger oil with a spray bottle sprayer (it does stink badly) then just remove the 10 or so bolts that hold the snout to the housing. Remember to keep track of where they go, some are different lengths.
You may have to use a rubber mallet, or your hand to hit the snout around to break the gaskets loose. Pull off the old black hockey puck looking thing (coupler) clean out the snout, attach new coupler, then reassemble and put new supercharger oil back in, and your rattle will be gone, at least for another 100k miles.
Best place to get a coupler is at,

Costs about 30, plus the few bottles of oil for the supercharger.

Supercharger leak on 2001 buick regal gs


maybe it has too much supercharger oil in the supercharger , that maybe be true what they say , it can be taken out , it should take two 4oz bottles, check your supercharger oil level, too much of it is not a good thing, overflow? it should take only the amount that is required, so dealership should know that
