Some advice please.
I've had problems starting my 4.4 V8 L322 since December when it wouldn't start at all during temps below zero.
Once the weather had warmed up it started from "cold" without any problem.
Once hot though, 50% of the time it will crank over (very healthy speed) and then splutter into life seeming to be firing on only a few cylinders but then it clears and runs perfectly. The other 50% of the time it fires up straight away.
Once running is seems to run perfectly.
The engine management light would also randomly come on whilst driving.
Fault codes showed 2 lambda sensors were knackered. All 4 lambdas were replaced but still struggled to start.
Since then the following have been replaced:
Fuel pump
Fuel filter
Fuel purge valve.
Local independent garage (Mansfield 4x4 in Bury St Edmunds) don't know what to do now.
Engine light is on again, showing P0430 - Bank 2 CAT Efficiency Below Theshold.
Can anyone suggest where I should look to get the starting problem sorted please, which may well be related to the most recent fault code,...... getting fed up with garage bills and not curing the problem.
Thanks
