EDIT: not to spoil the "who done it", but the fuel pump was the problem, saturated with dust and fine sand. See this link
Thought I'd put this out to the general brain trust and also see if there are any auto mechanic shops in Moab that are recommended.
I started having power drop off issues while accelerating yesterday (very minor), but today they became a major problem. The power will drop dramatically, my scan gauge comes up with p0171 and sometimes p0174 (lean mixture errors, both), and I get the "engine check, vsc, etc." christmas tree lights on dash.
p0171 and p0174 are lean mixture errors that recommend cleaning the MAF (which was done before the trip and again today after the error - no effect), checking air filter (done, clean), and checking vacuum hoses (done, and as best I can tell, fine). I checked out the following link, which seems similar to my error, but mine is intermittent:

Also, I had tried to see if it was low-grade gas that was doing it. On less than 1/4 tank full, I filled with premium. Thought I was a genius as it ran great and at full power (up hill past Arches and at like 75mph), but after turning around and coming back to Moab, I got it again slightly. It seems to get worse as the tank empties alittle, but maybe I'm imagining that. Based on the above thread, I will change my spark plugs tomorrow, but I'm running out of ideas.
That brings me to: any good auto place in Moab that might have a clue about our FJC engines and systems?
Thanks :cowfrown:
