87 n/a base

my fc used to not idle so i took the intake manifold off and looked for vacuum leaks. i searched and fixed any loose ends, put it all back together and now it wont even run for 4 secs. it can stay on for maybe 8 secs if i tap the gas pedal. i rechecked everything but i am stumped.

 

when you put the intake manifold back on it most likley didnt sit right. take it off again, clean both surfaces, replace the gasket, and put it back together. If theres a leek there then its the biggest vac leak u can get ha. Make sure u didnt unclip a fuel injector on accident too.
