Dead Injectors?

Postby th3k1d » Sat Apr 12, 2014 4:16 pm

So I think my mx5 may have 1 or 2 dead injectors but im not 100% sure.... it runs like a sick rx7 puttering and struggles to make any power even when it hits boost... I have changed the leads, plugs and also the coils but that hasn't worked... when I remover the spark plugs all 4 are dirty even after I clean them and put them back in so they must all be working but the strange thing is when I unplug injectors 2 and 3 the idle on the car doesn't change... but it I unplug 1 or 4 it does... so im thinking maybe they are stuck open?

im running a NA6 with rx7 550cc injectors

any help would be awesome I can even post a vid on youtube if that would help
