[dsjunkie]

ok here it is...i drive an '89...i've over heated twice in a month due to low water....last time i did it was last friday.....i filled it back up w/ water....i checked it yesterday and the water was all gone (but i wasnt overheating yet....*phew*)....now today my car is starting to idle real high (around 1200-1500 rpms) when i'm at a stop and when i let go of the clutch and open up the throddle some my car tries to jump back down to normal idle speed and i'm trying to accellerate...finally i have to rev it around 3500 and drop the clutch to get it to go....once i get going it runs fine.....what do you think?  please help me!!! i dont want it to be what i think it is, a cracked head leaking water into my engine and screwing things up (or it could be a head gasket....not as bad but still requires a bit of $$$$)thanks!!

check your oil. If it looks like milky white then you could have a problem. I would also check your radiator to make sure its not leaking.

Do a pressure check on your cooling system to see if it has any leaks. Do a compression check to see if your head gasket is shot. The results should be very clear if you do have a cracked or blown head.

if white smoke is puffing out of the exhaust, then it is the head gasket. but check the oil and spark plugs and see if there is no leaks that are falling onthe ground
