Help!! RPM drops

[Offroad vx]

Checking to see if anyone has the answer. A couple days ago I was driving and my VX seemed to miss a little but was fine. 2 days later I had driven to the store and when I went to leave my VX would start but then the rpm's would immeadiatly drop and it would die, tried it three more times still kept dying, but I hadn't completly turned the key off. After I did that it started and was fine until today. While I was driving it missed again and this time I noticed the rpm's dropped but it kept running. Anyone one know what senser or computer chip it could be I'm thinking that's what is. Thanks

could be fuel pressure regulator.. when mine went bad if i only let it sit for a a short period of time, it would turn over and die instantly.. unless i revved it up really high as i started then i could keep it running long enough to level out the rpms and it would be okay

Probably you just need to clean idle air control valve and throttle valve with carb cleaner.
