Default Engine judder

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.

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.

check the fuel pressure regulator - pull the vacuum hose off and see if any fuel drips out

Thanks. Not spark plugs then? Bought her 12 months ago with 153k and don’t know when they were last changed.

does your model have the coil packs or wire loom? If you have the wires like the 850s, look for a date code - if the wires are over 5 years replace those along with the cap, rotor and plugs. replacing plugs is easy enough - stick with OEMs as the platinum/iridiums etc don't burn any better.
