Do the spark plugs play a part when the ute is running on gas?
Also gregned mine could be mechanical and could bypass all sensors, I am going to pull the throttle body apart this weekend and clean that and the idle air control valve - do the simple stuff first.
I have checked the engine for vacuum leaks and can't find any, would a plug and play computer (mechanics) say what the problem is?

Once it's warmed up back on petrol it still drops engine revs.
I have fitted a new air filter, cleaned throttle butterfly's.
It's strange it's just rough on the petrol - that couldn't be vaccume hose because that would be rough on both?
Possibly fuel filter?
Pretty stuck so help out is you can - thanks
