vacuum leak? help please

Hey, can anyone help me pin-point a problem please?

when my car gets hot (after i drive it for a while when its roughly 95 out) and i pull up to a red light or have to stop, my car tries to pull forward, so i either have to hold the brake really hard, or if i slip it into neutral it rev's up real high then lets off, then when i go to leave from the light (put it back in drive) and take off it feels like it bogs really hard.

what could that be?

also, my brake light is on, as well as my ABS INOP light any suggestions?

Did you check/listen for a hissing sound (leak) under the hood? Sounds like a vacuum leak. Just check everything. It doesn't take very long.

Doesn't sound like a tune-up type problem to me. Do you have a labtop? You could buy a cable and download Freescan or PCMComm (both for free) and check your MAP sensor readings. That will tell you if you have a vacuum leak or not (most likely). Cables are like $45 from Mastach.com. Maybe you should inspect all of your hoses and fittings. Start with the brake hose.
