Im having an issue with my dual fuel ford fairmont, when im on petrol and rev it up or let it idle the car stutters, its not a miss fire like most will say because it runs and idles perfectly on gas, ive also recently replaced the fuel filter and have also recently cleaned and replaced the filter baskets etc on my injectors. So now I am not sure what it is? Has anyone else had this issue?

could be a dieing fuel pump?

Ahh! I never checked that but it has been replaced but only with a second hand one. Couldnt hurt to buy a new one and replace it.

bump.. anyone else know what it possibly could be? my dad (who is a mechanic) seems to think that its only on the one cylinder that its happening but im not too sure
