what are the symptoms of a leaking injector?

[stlunatics2oo3]

okay i have changed my original camaro 3.4 engine with a used one from a junk yard that had 70k miles on it seemed good running at the time. well the problem is i am only getting 13mpg and I don't like it lol. i am thinking its a leaking injector. cause i have new ignition control module, plugs, wires, k&n intake, all fluids changed. the car seems to run okay but i was havin problems with plugs for awhile cause they seemed to foul out which makes me feel the injector problem.


so please enlighten me on what a leaking injector might make a car act like and or any insite to my problem.

thank you in advance

have you changed the fuel filter at all yet? That could be another possiblity, but it would bog more if it was the fuel filter.

are the o2 sensers working properly?

[stlunatics2oo3]

yes new o2 sensors and new fuel filer and it has no catalytic converter

are you running in a closed loop fuel system...what kind of t stat are you running, whats your engine temp?

[stlunatics2oo3]

the engine t-stat is stock and everything runs right just my mileage is really bad and the only thing i can think it can be is the injectors are clogged or something

[BobbyZ72]

if the injectors were clogged the engine would run like crap. I really dont think your injectors have anything to do with it.

hmm well i have a spare set from my old engine that i know are good and i am going to put them on there see what happens ? iunoo thanks guys for all your input.

also can i take the injectors and rail out without taking the plenum off ? thanks
