Intake Manifold question.

[slavic98tj]

#6 looks odd...

#5 (and the rest of them... 4,3,2,1) Look a bit dirty/gooy on the inside. Which is normal looking becuase that is where the fuel injection is being taken place...

But #6 looks dry/ clean and that worries me becuase its the only one that looks like that.

Is fuel not getting to it?

My first guess would be you have no spark on that cylinder keeping it clean of burnt fuel/air mixture.

What does the plug look like and is the injector working?

Throw a '99+ intake on while you have it off, much better flow/performance.
