p0201 p0202 p0204 p0205 p0206 p0208 popped up on my scanner all at once along with 02 sensor and intake air sensor. It runs and drives but I can't let the rpm get below 1000 so with that being said when it starts you have to hold the pedal down half way and it will hit rev limits when it starts. Ive checked power with ignition on at the injectors and all read 3.4v I'm pretty tech savvy when it comes to a lot of things but this is mind boggling. I'm in the middle of wire tracing for bad wires I found a couple so far but I have a lot more to go. I guess my question is have any of you ran into this issue before

 

You should have 12 volts at the injectors.

What are you driving? What engine?
