Expert:  sprinkles08 replied 2 months ago.

Hello and welcome to Justanswer!

There are quite a few things that could cause the engine to run rough and it will most likely take some testing while the problem is happening to determine exactly what is going on.

The first step in diagnosing the problem would be to use a scan tool or code reader to see if any fault codes are setting. Has this been done?

Customer: replied 2 months ago.
no i havent used scan tools yet. do u know any scan tools i can bay to check for motor codes ?
Customer: replied 2 months ago.
i have search internet and there is lot of scan tools but , i dont know which one a can use to my car.
Expert:  sprinkles08 replied 2 months ago.

Any CAN bus capable OBDII code reader would be a good start. An actual scan tool starts at around $2,000 for an entry level unit but there are inexpensive code readers, many of which will allow for the reading of some basic engine data.

I also think mybe there is a problem with ac clutch . I wonder if its possible to check or change clutch, in place not take out ac compressor . what u think ?
Expert:  sprinkles08 replied 2 months ago.

What are you seeing that leads you to believe there is a problem with the compressor clutch?

Customer: replied 2 months ago.
because when i turn off ac car starts jerking
Customer: replied 2 months ago.
when ac is on there is no problem with jerking when car accelerate
Expert:  sprinkles08 replied 2 months ago.

If there was an issue with the a/c clutch then the a/c wouldn't work at all or would work intermittently.

Customer: replied 2 months ago.
