Hi chris it is possibly your egr valve or air flow meter or possibly the lambda sensor which is giving you trouble you can clean out agr with carb cleaner as for airflow meter you will have to buy a new one or a used one. the oxygen sensor can be checked with anyone who has obd software most local garages can do this they will also be able to check airflow meter at a cost of about £30 to £40

hi mate

check with: MAF sensor and clean throttle and check with all sparks. the problem must be there.

Firstly check for any leaks in the inlet system and also the engine coolant temp sensor electrical connections are clean and sound.:)
