1996 ford Econoline 150 5.8L
Thank you may I ask you if you would happen to know what maybe the top 3 reasons I am running lean with low idle. It's a 5.8 liter V8 Econoline 150 just looking for suggestions and where I should probably check first so appreciate your time thank you. I have a baby on the way with a tight income and just want to get the van ready for my baby thank you
