87 stang 5.0 5 spd

at turnds or when i come to a stop idle slowly drops till it dies what could it be?

fuel gauge jumps to full tank when i go over bumps and stays at full till i turn it off?

is there away i can check for eng codes without a scanner?

the k member is it bolted on or welded on?

is there any way to polish up my intake manifold?

where is the clutch quadrant located at?

thank you
