yesterday i managed to pull off my uim/tb to look for any leaking vac lines (pretty sure we found it) so i took care of that and today when i started the car, the idle stayed right around 2500 rpms and didn't drop like it normally would. also, the car will not go over 4,1k rpms no matter how you accelerate. (before you could slowly accelerate the car up to 6k rpms.) i think what may be causing this is the throttle cable being a bit loose. before we pulled it it had tension but now there is slack to it.

i believe i may be leaking fuel also... i looked at the fuel rails right after running the car and found that there was a leak and i'm fairly sure it's fuel.

any good tests/remedies for this?
thanks
