Car idles fine and accelerates fine but when trying to maintain constant speed-it chugs. Any ideas as to what is going on?
What speed are you going when it chugs?
It could be as simple as a bad spark plug or a spark plug wire/boot grounding out.
When spark plug boots get old, the rubber cracks and lets voltage arc out the side and to the engine instead of through the plug.
This will be most noticeable when trying to maintain a speed of over 40 mph, or under mild acceleration.
The reason for being noticeable at this speed/acceleration level is that the transmission torque converter will be locked, transferring the vibration from any engine miss straight through to the wheels.

i have the exact same car. And after a lot of searching, found the EXACT cause for this. Its your TCC switch (torque converter clutch switch). It has somethign to do with your transmission, and kicking the car into overdrive at certain speeds for fuel economy. Anyway, mine would stall out after driving for more than 15- 20 minutes, especially at highway speeds, which when you think about it - is the speed if you had a manual/stick - you would be shifting into the highest gear. Well, this chip or whatever it is basically gets "stuck" in high gear. And when you come to a stop, its like trying to get going in 4th gear on a manual from a dead stop. NOT happening!
I checked with a few people and did some searchign online - and found out all you have to do is unplug the wire leading into your transmission (not a car guy so I'm not sure exactlyif that's what its plugged to, but on mine ,same model and year as yours, it was blue on the very front on the engine way down dead center almost if you're standing in the front of the car looking down). I believe it was a 4pin connector when you unplug it, but I'd have to go doublecheck. NOthing at all bad happens from donig this - all it does is you lose about 3-5 mpg when you drive. I still get 25-27 mpg. If your car isn't in awesome codition and you dont want the headache of some mechanic taking everything apart to get inside the transmission to replace a dumb chip that just kicks your car into overdrive, I'd go this route. Worked for me.
I have checked all over online - and everyone who had this problem and unplugged it, had no problems ever. NO side effects. One guy says he's run up 100,000 miles since then and still runs like a top! If you need more info or whatever - email me. I dont mind. I'd love to know I'm helping someone out so they dont have to deal with it as long as I did! [email protected]

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.

The way this car was made is for this problem to ONLY be fixed by the dealer! No other repair shop just cost me $700+ dollars. There are no other solutions. Sorry.The dealer will say it's a cluster.It's because of the built in security system, and no it can be removed.
SOURCE: car has no power and sounds like its starving for fuel. please help!
It may not neccessarily be starving for fuel, but may be begging to exhale. Your catalytic converter may be clogged. This will cause a loss of power.

they might be on the compressor itself,with silver aluminum caps on them ,that unscerw ,otherwise follow the lines, they have to be there somewhere
