My 2000 NB manual has 80,000mi. Oil / filter change within 1,000mi. Fuel filter changed within 5,000mi. Snow screen and MAF cleaned and air filter changed within 500mi. Completely at random the vehicle will start and go into a low power mode. She will idle at 900rpm then hit 1250rpm with accelerator floored and extremely heavy exhaust smoke. Typically, if she is shut-down and let set for a few minutes, she will start and run without issue. Not popping any codes or CEL. When she is running, she is averaging 41 miles to gallon and runs fine.

Thanks for any help,
Ginzu

Not temprature related? Maybe something sticking a bit? but what I don't know. That's a strange one, I'll give you that lol.

sounds like low boost? maybe a leak?

41 seems a tad on the low side..
when mine was runnin' well, i struggled to get it below 43 or 45 when I drove it HARD.
you do all city driving? if so its not so bad then.
