Default Help with PO200 code

What causes the PO200 code, injector circuit malfunction? It seems to come and go. Car runs fine until the code pops up,then runs like ****. It seems like it's cutting back on timing.I've ohm the wires out,put noid light on all connectors, everything checks out O.K. Any help would be appreciated, Thanks George

Typically means the injector driver in the PCM is flaking out.

Yes, I also thought about that but my tuner said he has put in a differnent PCM and it still has the same problem. Could it be anything else? Thanks George
