Hi everyone, i have a 1st gen mazda6 2005 model ,2.3l engine.it will start nicely but the moment it has to drop the revs after starting it starts to jerk or cuts ,anyone can help.
I dropped it to the dealer and there said there changed plugs but it is still the same.

From my experience, it's a misfire. Try to check for a code with obd2 scanner to identify which cylinder is misfiring, or you could change all 4 coil packs just to make sure and don't have to worry about it down the road
