i have a 1990 n/a. i just took the entire intake manifold off and removed 5th and 6th ports. after putting everything back together im having some weird issues. When driving the car runs fine. when i left off the gas i get some more backfiring then usual. if i coast in neutral the idle stays at 1k. when i come to a stop the idle drops and jumps 0-1k and then dies? any thoughts? i also broke the throttle cable bracket and kind of made my own could i have not set the tension right?

 

could this be caused by a bad gasket between the lim and uim? i think the one on there is pretty shot

 

damn leaky injectors....fixed
