My volvo 240 1929 started out stalling when I let off the gas like when at stop lights and things. And it all so stumbles on acceleration after a stop. It seems to be lacking power and useing lots of gas too. And when its cold it has trouble starting. And just the other day I was driving down the road pushing the gass and the gass just pedal just stoped working and it was bearly going like 10 mph. Does any one know what it needs im thanking fuel filter or fuel injection maybe igniton timing I really have no idea.
