Spray some carb cleaner around the throttle body, and injector seals, it is common to see leaks there, can you hear anything? is your car idling high?

Buy a vacuum tester from autozone :)

it wasd idling fine most of the time (with the exception of once or twice when it was really cold), but i had a cel for my iac valve and i couldn't figure it out. well my dumb ass reused my throttle body gasket cause it looked fine and i din't want to wait for advanced auto parts to overnight one for 2 dollars. i finally after 1 month figured that this was the only thing that it could be unless my iac valve was just bad, so i ordered one, changed it out and voala! i was gonna buy a vacuum gauge to see if i did in fact have a leak, but i dind't know what the manifold vacuum was suppose to read, so i held off and figured i would try the tb gasket first, good thing because it only cost 2 bucks and the vacuum gage was 20 bucks :P

yeah, well a while ago (back in june) i was posting because i did my first engine swap ;D i swapped a newer b18b into my 93 teg because i hydrolocked the 18a, well, i got everything out, all accessories, tranny, harness, dizzy, everything onto the new longblock and put back together in a little over a day, but then it took me a week to get it running because my firing order was wrong ::) i couldn't figure it out, i knew it was something with my dizzy becaue i was getting a ---- load of fuel and foulin out plugs every 20 minutes :-X after buying a new rotor, coil, cap and more plugs (about my 5th set by now), i looked in my manual again and realized that the pic of the dizzy they had was sideways ;D

did your car bounce at idle? my friend (yungtuner)has that problem. we took his TB off to replace the TPS and when we put it back on after it warms up it revs to 2k then drops to 800rpm. prolly juse needs the TB gasket cause we reused the old one.
