Got my car checked at a professional electric mechanic last week and he said that there's no problem with the alternator and the whole electric stuff in the car in general however the car drives fine if i dont drive it for a couple of days, but when i drive it for a while after a couple of starts the idling problem returns and it's intermittent! i also asked him if it could be the brake servo and he said that an air leak wont cause idling issues like the one i have. im still debugging and looking for the problem i would love to get some help

What about the oxygen sensor? Is there a chance that i have a faulty one?

Mine is not like that mine is good And if i had an air leak i think the misfiring would be consistent, mine is sometimes rough and sometimes the idling is smooth, and i feel like the engine is loud

The servo hose is fine i think, my brake servo works fine

I took it to three professional electric garages and no codes show up, also i replaced the throttle body and the tps sensor and i dont think i have a problem with the maf sensor

Thank you so much!

Are you sure? but why is the esp and low tire pressure light up?

I have a 1.2 tsi skoda fabia 2011, and i have some serious idling issues! For some reason it’s inconsistent! Which means that sometimes it idles fine and sometimes it idles roughly and one cylinder shuts down then the epc lights up. Usually when this happens, two lights light up, the traction control light and the low tire pressure! They light up and the engine struggles to idle. But when i start moving the two lights go away! This problem only happens at a stop, i have to mention that i took the car to alot of garages and no one seems to solve the issue, i have replace the spark plugs, coilpacks, fuel injectors, fuel filters, spark plug cables, fuse box and basically everything and the car still randomly idles roughly at stops. Anyone can help me diagnose the problem!?

I have a 2011 skoda fabia 1.2 tsi 105 hp, and recently it started misfiring at idle, the weird thing is that i have replaced everything (coil packs, spark plugs, cables, fuel injectors and fuel filter) it lights up the ESP light and the low thre pressure and then it stars to idle roughly…. But as soon as i go the roughness is gone! if anyone had this issue please let me know
