95 Lsh

Ok I got a 95 LSH for the winter to save some milage on my new car. Anyway It runs pretty good but I noticed that when I first start the car it ildles good but if I dont let warm up a bit it will sputter or jerk when you accellerate. This only happens once and for a second then the car runs great. I changed the spark plugs and that didn't fix it but I am getting around 32 MPG (according to the overhead console). Its not that big of a deal as it does work good if I let it warm up for a couple minutes first. I have read it might be the intake gasket but I didn't want to do that if it could be something else.
Any idea's be great.

Thanks

Ok after reading a lot of other post here I will try to replace the intake gaskets. Since it runs pretty good right now, does anyone think that I can put if off for a while or should it be done soonest?

Thanks

Ok I went and got a can of quick start and sprayed all around the intake and the vacume hoses but I didn't notice any change in the engine sound. Could it be the egr valve? If so where is it located? I don't have a manual to go by.

Thanks
