Seat ibiza cupra 2010 power loss

[Agentb]

Hey guys ,new here and found this forum on the internet, I got ibiza cupra 2010 1.4 tsi 180 hp,
It's a second hand got it a month ago from a car garage (from Israel and cars here are real expensive and it was a nice deal)
I was driving in the late month and sometimes the check engine light would turn on blicker for a few secs and dissappear, checked in the garage and found nothing, today as I was driving in the highway I couldn't accelerate, as I was pushing the gas fully it would Rev but no push but the car would accelerate but really slow as I'm bellow 3000 Rev I think , then I pulled over turned off the car and then it worked normally again with no problems ,I would out it in the garage tomorrow or Sunday next week but any thoughts what might cause it and should I be concerned?

So, you had a blinking check engine light which means the car was misfiring and entered safe mode.
You could start by replacing all spark plugs and maybe all coil packs (coil plugs should last a long time but their performance decreases with age). How many miles does the car have ?

The car has 140000 km on it ,
I was at the garage today be checked the spark plugs and coil plugs and it was fine , had 2 mechanics on the car ,the car started blowing white smoke for the exhaust, then when he checked there was a leek from the cooler that cause shorts on some electric parts that's why the car is misfiring , what do you think?

You should short this problem out first. Any chance of a blown head gasket or piston failure ?

I booked a check in Sunday, hope it's all good and something cheap like injector

Update:so the white smoke apparently comes when I start the car when it's cold or when it's not on a flat surface but after reving a little and the car warms up it stops

So in the end ,in the garage he checked any system error and said the throttle body was failing ,after changing it ,didn't feel any power loss anymore butt the car one time smoked in the evening after not touching the car for couple of hours ,called the mechanic and he will check the cat again tomorrow, after all its an expensive part to replace .
Think he's right on that part?
He also said maybe it's leftover ,and also there's a leak in the cooling system he found the tube that has a leek in

it will be fixed after the parts will arrive

Is it the throttle body or the flap that diverts the air to the turbo/compressor ?
