ok did a leak down held 160 on all for at lease ten min. when you pull the plug wire off #1 the idle doesnt change. still runs like shi! All plugs are firing and injectors are working what am I missing?????

 

what do u mean u pull the wire u talking baout plug wires?

 

yes

 

when you take off a spark plug ur car would would feal like it wants to turn it off.

 

1 and 4 no change 2 3 car runs worse.
there is a change when you remove 2&3 car seems like its only running on 2 cylinders.

 

more info needed. did u just do a mpfi swap? change something? whats the year of the car and what ecu are u using if not the stock one?

 

88 civic hatch ecu that came with the swap.

 

on mine the fourth cyl (closest to the distributor) had crank pressure but not pressure when running. i tested the plugs and wires and they were fine with a new dist. i took the head apart and found out the valves, mainly the exhaust were f***ed up. so i just did a zc swap.
