Hi all

I have EML on.. this is whats coming up. Whats going on? Can anyone shed any light on this issue

After car is driven for around 20-30 mins & gets to temperature it judders / vibrates ... & its more so the case if you would go hard on acceleration but if you gently accelerate its not so bad

Its been doin this for past 8-9 months & the EML has been on for past month .. iv had it scanned 3 times & its same

Iv searched each code online & the codes are representative of "vacuum" or not enough air passing through. Duno if its the oxygen sensor or vacuum pump?

Won’t be vac pump as that’s only there for brake servo on them.

you certainly have an 02 sensor issue with the heating part showing failed, given it’s only after warming up so it’s closed loop it’s quite possible the sensor side of it is faulty.

I would change that sensor,clear codes then see how it goes
