Hey whats up everyone. ok let me apalogize in advance for my ignorance (but i guess thats why these forums exist)

OK i was having a rough running problem on my 91 max ge and it turns out that one of my injectors has died. so i am looking into the options and doing my research of whats involved to change them. what turns up is that i have to know whether my injector has a "blue dot" or a "black dot". Now i have a single cam engine and i suppose the dual cam has a different fuel injector, at least thats the only explanaition i can think of. but i mean come on, doesnt it sound a little stupid for that to be the only way to differentiate between the injectors. it really doesnt amke any sense to me. i mean thats the best thing the dealer can think of is to use different color dots??\

ONce a gain i aapalogize if this is just ignorance, but will someone please explain the reason for the 2 different injectors and the difference between them. also, before i pull my intake manifold, which kind of injectors do i have? thanx alot

 

get a new blue dot and be done with it.
NO I won't say why

 

hey, thanx a lot for the reply, but i was hoping to get some more information than that.

 

I know you were, but the rest of the info is pointless.

 

so what youre saying is that it doesnt matter what color i have on my 1991 now. as long i replace it with a blue dot injector, ill be OK??

 

yes, just be sure to get new
