New owner already got problems

only had the Freelander a couple of weeks all was fine till I gave it a shot of redx injector cleaner. Now it's a pig to start from cold, the engine intially fires and runs fine for 5 to 10 seconds then dies then takes at least half dozen tries to get running, once it is running it won't rev up just hunts at tick over. The other problem I have is the engine has no power till its warmed up, don't know if they both linked. I have changed the fuel filter and the crank case breather filter, any ideas?

Search for HPFP O'ring, this might answer your question.
Also crank position sensor and cam position sensor are possibilities.
I'm guessing it's a TD4 diesel.

Ah yeah it's a td4 on a 51 plate. Cheers I'll have a look tonight
