99ta Posted August 5, 2009 Report Share Posted August 5, 2009 I have a 97 z71 with the vortec 5.7. It has been running pretty bad lately. Has a miss at cruising speeds. pulled the plugs (which only have about 5k on them.) and the drivers side looked fine but the passenger side they all were jet black. Got some advice that a spider injector could have cracked and it was over compensating adding fuel to that side. so I took the intake off to see the injectors. no leaks. now my question is how do I clean them and with what? soak, just spray them with something? as for the miss, I am going to try the cats now. I have done, fuel pump, filter, plugs, wires, distributor, cap, and rotor. Eric Quote Link to comment Share on other sites More sharing options...
koolrayz Posted August 5, 2009 Report Share Posted August 5, 2009 best bet is to send them off to get cleaned and flowed. I sent a set to paradise racing for my dad. It was only $10 per injector Quote Link to comment Share on other sites More sharing options...
Cordell Posted August 5, 2009 Report Share Posted August 5, 2009 That spider injector shit sucks ass, I recently replaced the whole set-up on a 4.3 vortec and it had been redesigned. Soaking the set-up usually makes it worse, and to the best of my knowlege you're stuck replacing the whole mess. Prabably better off that way, maybe you'll get the newer set-up with injectors and no "popits". Quote Link to comment Share on other sites More sharing options...

99ta Posted August 5, 2009 Author Report Share Posted August 5, 2009 thanks guys, I have few other things to check before I go spending $300+ on new injectors. Quote Link to comment Share on other sites More sharing options...
99ta Posted August 5, 2009 Author Report Share Posted August 5, 2009 What other explenations would cause all four passenger side plugs to be burnt black? Would CATS do that? Quote Link to comment Share on other sites More sharing options...
