Hey everyone, ive had this ECO 2011 for 4 months now and i have around 150 000 km on it. (93 000 miles)
A week ago ive sent it to a dealership because ive had temp issues so using the 14371 tsb i made them change the water pump.
They also told me that the vavle cover was cracked so they changed it. (i had a p1107 code) wich fixed it.)
but since then ive had really weird throttle response.

When im pushing the pedal at maybe 70 or 80% the engine starts lagging really baddly. whe RPMs starts going up and down non stop.
i was wondering if any of you had the same problem and if de dealership might have touched something they shouldn't.

i verified the MAF sensor and i seems fine. other than that i havent had much time to look into it.

Thanks and im eager to help with pictures or torque charts since i have the full version.

Spark plugs would be my first guess. Spark blowout starts at higher RPMs under load.
