2K rpm max-water in fuel?
I think I have some water in fuel. Here's the situation. LBZ, no mods, 200k miles, great engine
up to now no problems.
In tow mode. Replaced FF 2 weeks ago. Towing 10K lb TT. After driving for about 70miles I stop
for hwy construction. I take off again but now all I can get is 2K rpm and about 30mph. I limp
into town. Mech looks and says prime pump is leaking so he replaces it. I hook back up and take
off. All is good. About 20miles out I stop again. Start going, same thing. I go back to mech,
he changes fuel filter. Seems great. This time 50 miles out. Same thing. I go about 30 miles
to next town. I reset engine codes with elm327 and Torque pro. I'm good again. 20 miles out I
start up a hill and rpm cuts back to 2k and ck engine again. I finally get to flat coastal
plains and reset codes again, all is good. Besides resetting code I can pull over cool down and
turn off motor. Start back up and all is good again. TT is in place so I will go home today
unloaded. I suspect that there will be no problem however, I suspect that there is water in the
fuel. I'm thinking of putting HEAT alcohol in there and try running out fuel. Any other ideas?
I think what is happening is that sensors are reporting water in fuel and computer is putting me
into limp mode.
Torque pro with elm327 no longer reports codes, it did before. Something changed. That's another thread.
