Is there a way to verify what quantity of fuel that is being sent to the injectors or the engine itself as a matter of fact. The reason I'm asking is I have reasons to believe some sensor or something is preventing all necessary fuel to be delivered to the engine. When I'm at 1000to2500 rpm, the car will kind of loose power, jerk but have all its power when I go full throttle. I also have some concerns that maybe the injectors are not properly working because of pour grounding. (from what I understand, injectors work by voltage pulse?) But how to test?
92 civic VX (has the VTEC-E)I know I have about 40psi of fuel pressure at the fuel filter output. I know the O2 sensor works (it's new), I have no check engines codes.
