After I filled up this morn my truck went into limp mode and couldn't go past 30 mph. My tuner gave me a p0087 code. I called the dealer they said low fuel pressure. I cleared the code and it seems like its running normal. My tune was on the hot stage and I put it back mild. Will I do any damage if I use it without taking it some where for a diagnostic? I got a camping trip planned and I don't want to make it worse.
