First of all, why did you change all the injectors? If you upgraded to larger injectors, you need to have the computer tuned to allow the correct injector firing rate, or you are just dumping too much fuel and this will cause major problems. We will need more info though like what size engine,what kind of injectors did you put in and why...|||Injector may be stuck open. Might be just 1 or two of them. Plug OBDII scanner in and see which cylinder is misfiring. then swap injectors and see the the code it gives follows to new cylinder. This will narrow down which is faulty.|||Are you sure you are throwing fuel out the tailpipe?
Faulty plug on one or more cylinders?
Improper fuel flow at the injector?
