Coolant temp sensor? Any fault codes?

No fault codes I did disconnect the temp sensor no difference 

I just took it for a 30 min drive and got codes 

P0107

P0402

Still suggestive of an intake leak, try disconnecting the EGR valve.

Ok I will try that but it a brand new egr valve this problem started only when I changed the egr valve as it had the same code and I did re adapt it this problem happened before I cleaned the egr valve and all pipes connecting to plus throttle body and it ran perfect for 2months

New parts have been known to be faulty too.

True but It ran perfect for 2 months and I'm getting a another one from the seller hope it works. Just took it for another 20 min drive and it's still rough idle but way better than before and on the drive no problem pulling through gears just coming to a stop or at idle 

One more thing I forgot to mention is that it runs better with the error codes when I erase the codes it gets worse

When you clear the codes you also reset the dynamic map so this again indicates that you have an air leak or the pre-cat lambda probe itself may be deteriorating.

I take lambda probe out and have a look and I had an air leak on my old car and the idle was high not low and never got no stalling just it wouldn't go past 30mph

I ordered a replacement egr valve and got a new temp sensor should arrive this week I update when I replaced them

Ok, good luck.

Thanks I just took the egr valve plug off and it's running way better about 900 rpm and it's staying there when it was working 100% rpm was about 700 just hope it stays like this 

Update it's was the egr valve in the Stuck open position now the error codes come it doesn't stall anymore as the ecu put it in default settings but If I clear the code it goes rough again till the code pops up again so got a replacement on it's way 

Thanks for everyone's help

Well put new egr valve and same problem again what can be the problem??? I can drive it with the engine light on but when it comes to the mot it be a fail this car really doing my nut in 

Did you adapt the engine ECU to the new EGR valve?

 

What year is the car? If it was first used before 1st July 2003, the MIL light isn't tested/relevant. 

8. Nuisance - MOT inspection manual: cars and passenger vehicles - Guidance - GOV.UK (www.gov.uk)

 

You need to inspect MIL fitted to:

• petrol vehicles with 4 or more wheels, not more than 8 passenger seats in addition to the driver’s seat and first used on or after 1 July 2003

No I'm waiting for the cable to arrive so I can adapt the new egr valve and it's 2005 last time I drove for half an hour and the egr valve code came up forgot which one now and it ran perfect but soon as I erase the codes it gets worse so I'm still driving it so the code comes up as I hate it stalling on ever corner but with the 1st egr valve all I done was cleaned TB and egr and all pipes connecting to and it ran perfect for 2 months never done a egr adaptation so got a replacement sent out which I installed and got the problem again  but I will wait for the cable to adapt egr valve and will update 

Just unplug the EGR valve and it should run sweetly.

It don't straight away it takes about 30 minutes to an hour of driving and stalling lol to get the codes up the only code that's comes up within 5 mins is the one saying my plug is not connected and I know I said before it was unplugged but I remember it wasn't unplugged then the codes come up after that I unplugged it and I need a permanent solution as it won't pass mot with engine light on even if I turn the light off ( which it will stay off for a few hours) it will fail on emissions. I just hope adaptation works if not I'm just selling it as it's doing my head in. Going back to a Astra as I had it for 8 years and only problems was normal wear n tear

I just blanked the egr valve off and that sorted the problem as my cable still not here yet will take blanking plate off when i get the cable
