my sr20 is not running right :/

[240sx_Guy]

my sr20 feels like it is losing gas. from what i have research it sounds like it is a vacuum leak.

symptoms:
car idols high 2k and then drops down to 1.2k. at 1.2 k the engine burps/pops ever few seconds, rhythmically.
when i launch in first from 1.2k to like 3k and put the clutch in, the car wants to stall while falling back down to idol.
today while driving, it felt like it was losing gas. every time i let off the gas it wanted to stall. i put more gas in and the problem continued...

i am worried and would like some help. thanks

Check out timing? burping at idle is normally something not formulating right. But it could very well be a vacuum leak, sounds like you need to get some throttle body cleaner and start squirting! Let us know if you find a solution for reference.
