Hello guys, I drive a Legacy 150hp petrol engine that was converted to LPG 30tkm ago and has now 120tkm on the clock. Sometimes starting with this car is incredibly rough. Not only cold, but at every traffic light again. This behavior occurs – if it occurs – equally in LPG as in petrol operation. I do not see any connection with the engine or ambient temperature. If this behavior occurs I see in the Torque that the EGR target value when giving gas etc fluctuated t (should he be too), however, I see with every change also short EGR errors in the range up to 50%. That the EGR valve does not react immediately, but needs a short time (substantially less than 1s) to change its value, seems to me now also reasonably plausible. My question is now whether you recommend me to clean the EGR valve? It is not that easy, therefore I do not want to get into the details without your feedback. Currently it fails because I do not The valve play has not yet been adjusted, according to the workshop this is not necessary due to the still low km performance on LPG. For cost reasons I would of course prefer the EGR anyway. What do you think about it? Thanks already, cucumber
