Up until very recently, my car has behaved perfectly for months on end which is very unusual!
Basically I can be in any gear at any speed and the engine will splutter/misfire very briefly, say for a second or two then clears itself.
It feels like a fuel starvation problem rather than ignition. This has been happening for a few days now and will happen consistently every few miles.
I am well aware of the high pressure fuel pump and regulator problems surrounding the z22yh engine as I have replaced the regualtor twice already!
There are no warning lights at all and no codes stored.
If my hp pump is about to go up the swany, surely I would have codes relating to low fuel pressure (P1191) like I did when the regulator went faulty?
I think I'll change the fuel filter for a start but any thoughts/advice would be greatly appreciated
