All sorts of 2002 SL1 Problems

Ok, so i have a 2002 SL1, i used it for traveling all throughout the US for two years and tracked on 75,000 miles. Now i got troubles. To start with, coolant leaks, though no puddles under car at all and cant seem to see the source, and i mean i refill the reservior twice a week. Then, oil is goin somewhere, but im not burning it. I have slightly a few drops under car, but not near enough drops as to what im losing. Now the big problem. Starts kinda rough like it wants to die until i pump the gas a couple times.....when its idling at red light it idles and low and i want to say it chugs or shakes a bit.....then when green light goes it bogs down and doesnt really want to go until about 2500 RPMs. Afraid to take it to Saturn becuase i have a full shop and can do the fixes myself with friends help, but not sure how else to find problems. I know its alot but anything you guys out there can help with would be great!!! Thanks!!!!!!

for the idle - clean the throdle body and EGR with sensor safe carb and choke cleaner, if you can, check fuel pressure, the fuel filter may be getting old and clogged

oil - i bet you are burning it. be sure the PCV valve is the OEM saturn peice, aftermarket brands can cause oil burning. also try the "MMO soak" in the how-to forum on saturnfans.com

coolent - have you done any work on the cooling system? even as little as taking off a hose? if you are SURE its not an external leak(not even a slow leak) then its a internal leak, it can be a blown head gasket/crack cylinder(white smoke out of exhaust or a lot of bubbles and foam in the reservior, some times but rarely it will dip in to the oil pan) or if its a auto transmission, it may but the radiator(coolent in transmission and/or ATF in coolent system)


anyway - you should check out the forums on saturnfans.com, these aren't uncommon problems.
