I replaced all the spark plugs MAF. But the car has a rough idle and sometimes struggles to accelerate and gives jerks 2-3 times every 10 minutes. And sometimes turns off in idle . Can someone help me what is causing it ? I also used Lucas injector cleaner as well. Thank you
How old are your air and fuel filters? Is your fuel pressure up to specification?
I used an obd 2 reader . I didn’t get any codes relating to fuel and air filter. I have Mass or Volume air Flow sensor code for circuit A but i changed it recently.

There are no codes for the air or fuel filters, and a car that old most likely does not have a sensor for fuel pressure. Those things need to be checked manually.

Did you install an OEM sensor or was it aftermarket? Does live data show it having reasonable output? Is upstream O2 sensor working properly? You may also want to check for a clogged catalytic converter using a back pressure gauge.
