Hello,

A vehicle can hessite due to a number of reasons.
It could be for having a dirty fuel filter or clog in the fuel line, vacuum leak, faulty mass air flow sensor. It can also hesitate due to having worn spark plugs.

The best course of action would be to look at the typical possible causes and take appropriate steps.

Take a look at this guide:

Go through the guide and let me know what you find or if you have any questions.
Thank you.

Thanks for your kind help. I found one wire of TPS was broken so I welded it. The vehicle is now much better than before. It only hesitates when the vehicle is running. Did not hesitate when there was no load on engine.
