Hello, I have the following problem with my Volvo V70 (1999 petrol smallest engine): After starting from time to time idling problems for a certain time, but then after a slight gas release they don’t show up at all. Acceleration problems from time to time, as if there was no power at all, increased at the beginning. Unfortunately, no MKL lights up, so that I can’t deduce anything from it. If the car then switches to LPG, all the problems seem to be fixed at once. Gasoline filter, pipe closed somewhere, petrol pump or relay? For example: I had the relay outside 3 months ago and even soldered it, so everything still fits. Gasoline pump can always be heard clearly running while turning the ignition key right now. Thank you for your help.
