It appears you have possibly a bad MAF sensor. It's in the intake duct. If its dirty, wash it off with CRC electrical cleaner. Do not touch, rub or brusj. dries quickly. See if this helps. Good Luck, Ned

Depending on the mileage of the vehicle sounds like the timing belt has stretched. If the coughing is when you give it gas but not when it is not under load timing belt would be my guess. Good luck and drive safe.

Check for sticking idle air control valve and stuck open EGR valve. Both are common causes for very rough engine operation due to fuel-air ratio being too far off. Also check for large vacuum leak such as from rubber hoses connecting PCV valve to intake. Feel around for squishy or oily rubber which would indicate a leaking hole in the rubber hoses.

Sounds like you have a plugged up catalytic converter. You cant clean them it will need replaced. If it is the 4cyl engine, the converter is the exhaust manifold on the front of the engine.

Same thing happened to me. I took it to the dealer, no choice. They told me that it is the engine. Didn't want to hear that, but I guess I have no choice.
