The two leading causes for the the dreaded P2A00 code is a leak in the intake piping after the MAF sensors or an exhaust leak before the primary O2 sensors.

So going to my mechanic and sealing the leak should get rid of Service Engine Soon light??

IIRC This code takes a "drive cycle" before it resets (assuming the problem condition went away). Unfortunately I can't remember what constitutes a drive cycle.

Take it to autozone have it diagnosed the code for free. It could be an exhaust leak had mine light up. Had to replace blown defective gaskets in the HFC. Problem solved.

Btw is it at blinking engine service light or a solid light on?
If is a blinking light you do have a misfire on one of your cylinder. That could be a reason for it being sluggish. You need to bring it back to the one who did your tune.
