When i accelerate from a start and cruising the car has a hard time accelerating. It shakes a lot and sputters. I replaced the spark plugs and air filter. What could it be???? Please i need help ASAP!
Is the engine lite on? if a misfire shows, and the plugs are new, could be coil or wires. how does it idle? maybe air leak between mass air flow sensor and throttlebody.
autozone will scan for free, they are just unable to clear it, if that helps any.

Is this a 2.4? I had one that the balance shaft belt broke and made the timing belt jump. Had the same symptoms as you. Vibration comes from the unbalanced oil pump shaft, sputtering could come from the timing being off.
May be the micro filter in the high pressure fuel pump. This pump is located in the engine bay. The vehicle also has a low pressure pump in the tank. If the high pressure pump is not delivering fuel to the fuel rail effectively in the GDI versions, the car will die under load. Its not a big job to do usually its a kit replacement with o rings and a micro filter. Probably a job for the serviceman.

The engine light has been on for quite a while, before this problem. I was getting ready to borrow a computer check and check the code but i haven't been able to. it idles very rough in drive, it shakes a lot. But in park it idles so so and then sometimes it shakes and then stops.
did anyone find the answer for this problem? my car is doing the same thing. i cant figure out what is wrong with it
idle air control valve....temp fix is to take off the air hose leading to it and spray with wd40...long term fix...go on ebay buy the part for 40-50$ and take 5 mins to replace it. the dealership will try to charge 900+
I changed the fuel pump, fuel filter, spark plugs, air filter, changed the oil, changed the tranny fluid, changed starter & my car is sputtering when I press on the gas & when I reach over 50mph my check engine light starts blinking...this is getting so frusterating to figure out what is wrong?? Someone please help!!??
Not sure if you ever fixed the problem but it sounds like a TPS throttle position sensor sometimes if you locate on the throttle linkage it will have a plug going to it disconnet it and see if the car accelerates most of the time it will stall if the check engine light is on you can take it to a Autozone if you have one near by and they will run the code amd let you know what part you need I would fugure it would be the TPS or Air Flow sensor both very simple to replace yourself.
