CX-7 engine stutters when floored at 60 kmph

Asked by Feb 11, 2016 at 01:58 AM about the 2009 Mazda CX-7

Question type: Maintenance & Repair

My end 2009 Mazda CX-7 with a 2.3 litre petrol engine + turbo stutters
when I floor it while moving around 60 kmph.

The engine is alright even if I floor it from rest. It's also alright if I step on
the gas pedal till about 95% while moving at 60 kmph.

Does the engine need more torque/power when floored while moving at 60
kmph compared to being floored from rest?

Things that I can think of are spark plugs, petrol filter/pump and air filter.
The one thing that I'm hoping is not the problem is the turbo.

I've heard that the CX-7 has a Throttle Position Sensor (TPS) and jerking
while accelerating is one of the symptoms. However, the other symptoms
are not present.  http://www.carboncleaningusa.com/throttle-position-
sensor/gas/mazda/323-1-6-l-82

Any idea what is causing this problem? Would the Mazda service centre be
able to trouble-shoot the problem through engine diagnostics alone?

I hope that they won't give me a list of possibilities which would mean that I
have to change multiple components one by one.

Changed my spark plugs and the problem went away.
