The latest issue is that my 97 transit has been losing power, this is more noticeable when trying to accelerate up hills but is noticeable across all driving and seems to be progressively getting worse, I am not sure where to start but I will list all of what I think may possibly be relevant in the hope of some helpful pointers.
- I did the epic to bosch conversion about 2 years ago with a pump/kit from dieselhead123, once the conversion was done it was pumping out the black smoke on full gas, I didn't adjust the pump just learnt to drive it without flooring it and making clouds
- Flooring it now produces no black smoke what so ever.
- I had the gearbox replaced with a second-hand one about 6 months due to a cracked bell housing.
- I then about a month ago had to replace the clutch fork which I did myself.
- After doing the clutch fork the idle was a bit lower so I adjusted the idle stop on the pump it was around this time that I noticed the loss of power, although thinking back it probably started earlier.
- Last week I had an issue with the engine not stopping when the ignition was turned off, tried giving it a rev at the same time to clear anything that might have been caught in the shut of valve but still didn't turn off so I stalled it. Since then though the issue hasn't happened again.]
- I am pretty sure this is a different issue but will list it just in case, when braking and going down through the gears, the brake pedal seems incremental when the rev's change, ie hit the brakes the pedal goes in a bit and feels firm, then on a change down the pedal needs to be pushed in a bit further to be firm and for the brakes to apply, and then again with another change down
My initial thought is to increase the fuel adjustment on the pump, although if this works I think it would likely only be temporary as it wouldn't be addressing what is causing the issue in the first place, the only other possibility I have come up with is that one of the reasons I have read that the shut of valve fails open can be due to metal debris from the pump failing.
