Injectors wet on top
Hi, not real familiar with fuel injection systems so I have a question. I have a 93 Silverado with a 350 with a throttle body. It won't pass idle emissions testing no matter what I've tried. I did notice that the tops of the injectors have puddles of gas on top of them. Is that normal or are they defective. Truck has 163K on it and theh were never touched. Thanks

I don't know much about the TBI trucks, but my guess is the injectors are leaking and adding more fuel than normal at idle so it may cause you to fail emissions.
