1999 7.3 exhibiting black smoke and power deficiency on rapid acceleration.

twentyover

Replaced the high-pressure oil pump, high-pressure lines, exhaust back pressure sensor, number 8 injector, and injector harness. The persistent problem I am experiencing is that at about 1800-2200 RPM, my vehicle emits black smoke, exhibits irregular power loss, and significantly loses power. I just encountered a P1211 code; during this occurrence, my ICP reading significantly decreases while my IPR increases, however it does not exceed 50%. Your assistance would be much appreciated. Is it typical to get no readings whatsoever about my glow plug condition on my diagnostic machine?

The PCM does not oversee the glow plug condition in the 49-state trucks. The Kalifornia model has a GPCM that need to be shown.

Acquire AutoEnginuity or Forscan, capture relevant data, and share it here. Observe RPM, MAP, EBP, intake manifold pressure, IPR duty cycle, and injector pulse width. Conduct a test drive that encompasses an instance of the aforementioned description. We may examine the data together to ascertain the current situation.

Upon replacing the HPOP, did you use your previous IPR?

I own an Autel device that provides all those measurements. I will document all of it tomorrow. I do not recall changing the IPR during the HPOP, so I suspect I reused it. Could a malfunctioning gasoline filter be a contributing factor?

The color of the filter indicates the presence of oil in the gasoline.

I concur that it resembles oil; replace the filter and inspect it after around 100 miles. If there is a fractured injector O-ring, you may be experiencing a loss of pressure. It would be beneficial to replace the IPR with OEM components only, since I have encountered many aftermarket options that are substandard.

Did you capture the picture immediately after removing the filter, or was it left outside in the sprinkler overnight? The water drops would induce apprehension in me.

No, it was not spending the whole night in the sprinkler. My wife was reprimanding me because I took it inside while it was still leaking petrol. I placed it in the sink.

I While en route to a client's residence, I inadvertently pushed the escape key on my computer, resulting in the loss of recorded data. Upon my arrival at the project site, the homeowner indicated that I must be leaking a substance, as he saw a lengthy trail of fluid extending from the road to his driveway. It is diesel fuel. I am currently uncertain about its origin. I do not want to dismantle it at a customer's residence. I will bring it home and inform you thereafter.
