Default Code P0200 injectors circuit *Please Help*

Ok got this code this morning, car runs horrible, u can hear how idle is unstable (Up and down). Acceleration is horrible fells like it just boggs and u can hear it bogging.

I pulled inject fuses and seem good. Bought new spark plug wires and plugs. Also searched on here and found some minor discussion on inj wire harness being ripped or cut. I searched driver and pass side and could not find any.

I can say that my inj wire harness looks dry from old electrical tape etc etc. Can't seem to find any exposed wires.

Could it be the O2 sensors?

Don't know what to do next. Anyone else fix this issue?

Thanks Old Geezer, I just wanted to know if there was a common problem. My injectors are trickflow 80lb/hr, I checked the wire harness and did not see anything abnormal just dry blk tape from heat. Am I missing something. Car runs really bad.

There are several possible causes for P0200. Here's a typical diagnostic for P0200.

I checked the injectors and are they supposed to be loose, meaning turning free play while they are in there place. I dont see any cuts of any sort. Do I have to cut the entire injector harness. Fuses seem ok.

Any suggestions.

Yes your injectors are supposed to be loose and able to turn. If you can check for +12v at the pink wire on the injector and see if you get +12V
