Hi!

I had the feeling my engine is not running at full power so I did the paperclip test and got error codes P0201, P0202 ,P0203, P0204 and P1690. I understood that i could ignore the P1690 but I'm a bit worried about the injectors. Note that the engine has been refittet to run on LPG-G3. Should i be worried or can I just ignore them?

Check the plugs to all 4 injectors, are they clean? dry? and fully pushed home until they click?

It sounds to me like the LPG system is not loading the petrol injector signals enough when running on LPG - hence the ECU thinks they are open circuit. Too much of a coincidence for all 4 to be complaining otherwise.

I suspect it's probably always been like this. Does it run any better on petrol? Do the codes clear and stay clear if the car is only run on petrol?

My thoughts exactly. I'll try resetting the ECU an just running on petrol. The thing is though, when I rev the engine up to about 4k RPM's It will sometimes give you a lot more power, instantly, like something switches on all of a sudden. Therefore i thought this had something to do with it. It might just be my imagination. i've only driven the car for a couple of days now so i don't really know what's 'normal'.
