    I have a Hyundai Coupe SFX which picks up really well but sometimes it starts to chug or looses power but only for a split second, more so immediatl;y after i fill it up. I have replaced the purge valve, put fuel cleaner throught the tank, replaced the fuel filter, wrapped up the leads to check for shorts, cleaned the injectors and put the car on the diagnostic scanner and no faults showed up. i am at a loss and sick of this happening.

This could be a multitude of things but my first suggestion would be to change the spark plugs. They are cheap and can be bought at any auto parts store.

SOURCE: rear wheel bearing hyundai coupe

just remove the wheel and count the teeth on the ring on the rear brake thats all you need to do. Since you can't drive it take it off and take it in to compare parts so you don't have to go back twice. You will need a new wheel seal and race and bearings.

SOURCE: car chugs and jerks like crazy while cruising

Determine whether the jerking is engine or transmission related. One way to determine if it is the transmission lock up converter is acting erratically is to down shift out of OD. And see if jerking persist. If it goes away suspect transmission to have problems with torque converter or TCC solenoid . If it doesn't go away determine whether or not the engine sounds to be misfiring. If so vehicle may require a tune up. Many vehicles can be diagnosed for free at your local Auto Zone.
