My car chugs (almost stalls). I can be going 1 mile an hour or 65 miles an hour (very random). It doesn't really matter if it's dry or wet out either. I thought at first it just might need dry gas so I put that in and it did nothing. It started getting pretty bad so I had it towed to the Hyundai dealership. They said I needed to change the cam sensor and crank sensor. I changed both of those and it is still doing it. I've changed the spark plugs and had the wiring looked at. I read a lot of your other stories but nobody seemed to have there cars act up going at high speeds. Do you think it's the fuel pump; I noticed that was what was recommended to most other people?

It could be the fuel pump or just a filter. I do, however, recommend checking fuel pump pressure.

Here is a HOW TO video to show you how. The gauge being used can usually be rented at a parts store.

Let me know if this helps. Just a side note, has anyone checked the catylatic converter for internal damage or being plugged?

The check engine light was on when this first starting happening. When I changed the cam and crank sensors it went off. It has come off and on here and there but at the moment it is off. It came on all of a sudden yesterday for a little while but not while it was acting up or anything. It's running okay as of today. When I use shell gas it seems to help but I know it's not the solution because it still does it once in a while.

If the check engine light was on, take the car to a nationally recognized parts store and have them scan the computer for codes. If the light was on, there should be a code stored. Most of these stores will do it for free, so there is no money out of pocket.

Let me know what you find.

There isn't a code at this time. The light isn't on right now either. Before I changed the cam sensor it said "cam sensor" but that code went away after I replaced the sensor. It still isn't fixed though because it still has it's hesitation/jerking moments here and there.
