I've got a 99 24 valve, just put a lift pump on it. The injection pump was replaced with a used one. The old pump misfired at idle, and started hard. This one runs smooth at idle, unless you rev it past 1500 when cold then it goes to missing. Once it's warm it has good power, and no longer misses. Also when its cold and you rev it you get a lot of white smoke. No codes are showing. If you try to drive it cold it has no power, once its warm it runs great. I'm at a loss here?
Thanks
