My 2005 Tucson GLS, with the 6 cylinder engine and automatic, is
stumbling badly when accelerating from a stop. I put my foot on the
gas and the car lurches while the tach swings up and down between
1000-2000 rpm. This started after my last fill up, so it may be a bad
tank of gas. I have an appointment with the dealer for next week.

Any ideas what I might be looking at?

By the way, there is no check engine light. The car runs fine once up
to speed and starts fine.

Just a piece of crap Hyundai; should have bought a GM

 

Check to see whether the air intake hose has pulled off the air flow
sensor. There’s a technical service bulletin about this issue.

If that’s the problem, you can probably just reattach the hose for
now. The fix is to replace the clamps with some that provide more
clamping force

Yeah, a bad tank of gas could have crudded up the fuel filter(s) o
got water in the carb/gas line, my guess
