Engine judder poor starting

[Steveskel]

Hi
Ive got a 1999 V70 2.5 petrol.
I’ve had problems starting when hot or cold, and in any weather. Battery is sound. It doesn’t appear to ignite unless you put your foot hard on the accelerator.

Ive started today twice in -2 first time. I’ve driven motorways for 60 miles.

I got home for an hour and it started first time. I drove for a mile and didn’t stop the engine. On the return trip the car started to shudder. When I accelerated in any gear. There is a slight petrol smell. I drove it at 70 for 3 miles but it hasn’t cleared.

Any ideas gratefully received. Thanks.
Plugs?
ps oil and fuel filters haven’t been changed in 12 months and I’ve had new wheel bearings both sides front 5 months ago.

It sounds like the fuel air mixture is too rich. Get a code reader on it and see if it has any complains.
