wet spark plugs

The rebuild is now more then ready to be pushed harder with close to 5000k on the motor. I find lots of power up top in the 3500-5500 rpm range but down low the car is still quite sluggish. I wouldnt think twice about it except for the fact that my front rotor plugs are always wet and clean when I pull them while the back are dry and crispy brown in color. Obviously I'm getting too much fuel down low but what could cause this?
I had my injectors cleaned and the buddy said
"the fuel just poured out of them"

My HKS filter is also getting yellow so that might be adding to the problems.

Any ideas?

send injectors to a place called RCengineering for a professional cleaning w/ flow specs.

but that would cost me close to 200 bucks. I live up in canada eh, so my money isnt worth that much eh!

I could probably buy 2 injectors for the price of sending them down there to get them checked...

I'm just hoping there could be a reason that they are pumping too much gas more then they are "untuned"

could an airleak around one of the intake manifold gaskets cause this?...

If you like playing around with the car, get down to the primaries & swap them front-to-back (or with the secondaries if ya want)...See if your problem rotor moves, or stays put. Then you'll know if you need the injectors cleaned/ replaced, or if it's something else (vac/ bleeder leak, bad spark, etc...)

The primaries are the "down low" ones...Get everything out of your way, swap the front to the back, then swap the secondaries (the "up high" ones) the same way- if your rear rotor plugs start to look like the front ones did, the injector(s) is your problem...Troubleshooting without paying any money, gotta love it!
