Hello,
I have a gulf edition, it takes so much fuel and sometimes the acceleration is stalled. it shows no light on the dash at all. I have serviced the nozzle, changed the plugs still the problem persisted. I took the car for a diagnosis and it showed only one error which is stability malfunction. I was told the plugs I bought was not original and that I should change them. some other person said I am using the wrong fuel for the car (I use Mobil 1). Please what do you suggest I do? if it is the plugs, so you have original plugs that I can buy and be sure that the issues will stop? Imagine travelling 300 km and the fuel finished entirely.
Please I need your advice. Thanks

put correct plugs in car then check fuel pressure with a gauge and look for a vacuum leak like a hose off etc. See link.
