Hi All,

I have 2000 acura tl with 201000 miles. Recently i had CEL on due to misfire. I changed the spark plugs and CEL went off. It came on again after two months with misfire codes. I thought it were plugs again. Before changing the spark plugs I seafoamed and then did oil change. I then changed the plugs and used NGK iridium IX. Now the car jerks a lot in idle and also in gear. I have noticed that it doesn't jerk at cold start. RPM at idle and in gear are stable and good.
I cleaned my EGR ports few week back as well.

Can anyone help with that please?

Make sure the plugs are gapped to the correct setting. An incorrect gap could cause misfires which is the jerking you are feeling.
