Chugging when I accelerate

first check No.5 spark plug wire closely...change if necessary....if good then change crankshaft position sensor.

Mike fuel filter may be dirty and plugging after running tank so low or possibly fuel pump has now weakened and is failing. Have vehicle scanned o see if diagnostic codes are stored to help diagnose.

fuel filter and pump

the fuel pump is going bad

sounds like your throwout bearing is on its way out

The fuel filter is probably full of metal too. (fuel starvation) replace it.

Still Under Warranty. Take it to local/nearest Authorized Hyundai Service Department.

When you ran out of gas, the pump probably pucked up crud from the bottom of tge tank and clogged the fuel filter - it's not uncommon. I'd change the fuel filter, and pick up a can of Seafoam (Walmart or any auto parts store). The next time you fill up, pour the Seafoam into the tank and fill up on top of it. That'll help clean the lines, tank, and injectors. Then you should be good to go.

Check your fuel pump or even your air intake could or might be loose or your putting cheap gas in your vehicle.
If your truck has a V8 I would suggest using 91 octane at Chevron or a Texaco.

it could be fuel pump problem plug leads ,coil pack
