What concerns me is the uneven injector flow. On startup, they should all tickle evenly together. If they don't, something is wrong in the rail. All of them SHOULD see the same flow and pressure, and should be getting the same signal from the PCM.

Default FIXED!

All injectors except the one I replaced were plugged on top in the small cone shaped screen. Cleaned the screens and rail and FPR. Started right up! Shortly thereafter it develpoed a miss. Plugged injector again I suppose. Goint to spend today flushing the fuel system again.

Thanks for everyone'* help! I have now invested about $800 in it, but it should be in good shape after this.
Question. After it started, the CEL was on. Missfire code? I am going to search web for codes and run these down.

THANKS AGAIN![/b]

Default Code

No more code. Cleared ECM. Flushed fuel system again. Light did not come back on. Missfire still there. Comes, goes. I think # 5 injector is sticking. When I pulled injector connectors one at a time with it running, #5 made no drop in RPM'*.
Also, the tach seems to read double what engine speed is. I know that when I raised RPM'* in park, that engine certainly did not sound like it was pegging 7K! What could that be?
