I had another thread in mechanics section but hope I might get more advice here.
I, ve just bought one a 2.0l petrol auto. It seems to be holding back at certain revs.
I put a new coil pack on it today and it seems a bit better. Not perfect.Took plugs out. They looked good but really smelt of petrol. Cleaned them , put them back. Thinking of changing fuel filter too. Any ideas please

Plug it in to a Lexia.

But no warning lights are on. So would it still find fault codes

[megamaniac]

Yes it could show faults without putting mil on. Does it start ok when hot?

[chasdad]

It always starts ok. Runs fine apart from the slight hesitation. Seems a bit worse when it's warm

[megamaniac]

Before you do anything else give it a good quality engine flush(forte or wurth) and some fresh fully synthetic oil.It may just be a sticking hydraulic follower.

Had it scanned today and has come up with camshaft position sensor so fingers crossed
