Hello, I'm young adult who recently inherited a FJ62 Landcruiser. In March of this year, I started noticing the idling was getting very weird, it was stumbling around 1-2k rpm, but never stalled. Last week I started it up to run an errand and it stalled out, won't idle at 1k or below. I have little to no knowledge of the engine in my truck, but I do know it's a 3F-E, and hasn't had engine issues before. It's been properly maintained. I just want to figure out if this is a known issue and can be fixed at home, or I need to get it to a mechanic. I already posted about it on reddit, but was told to come here. Several people mentioned it possibly being a vacuum line problem, and others said idle solenoid, fuel pressure regulator, fuel pressure dampers could be the issue. Thanks!! Love this truck, and I hate not driving it
