ok so my car overheated fro the first time ever today, had to get her towed :(
this is exactly what i did:
saw where the fluid was spilling from, it seemed like it was from the reserve originally (the plastic tube behind the driver headlight)
let the car cool for like 30 minutes, took the cap off the rad and it was empty..
put in 50/50 and while i poured i checked to see if it leaked, and it was from there..any ideas? tony?

I'm not down with the artsy picture. Is it leaking from your lower rad pipe?

so i discovered the leak was coming from the coolant lines..now a bigger issue, my gas pedal is stuck! i took off the intakes to get a better look, and the passenger side opens up a little but, but the driver side is stuck shut...do i need to replace to throttle body?

Most likely sticking due to either the throttle cable seizing or one of the linkages getting caught on something. Go under the hood and turn the throttle linkage by hand (not using the cable) and see if it binds. If it doesn't bind without moving the cable, it's most likely the cable needs to be lubed up.

Make sure the pcv's coming from the valve covers haven't backed out catching on the throttle linkage.

thats a simple nuts and bolts issue man, disconnect the cable and look at it really hard, you probably bent the shaft somehow
