My issue is that if I start my car (or drive around) and then shut it off, come back in like 2 or 3 minutes and start it, it will start immediately. But it will jump up to like 1500rpm, then the car will compensate by lowering the RPM's, but it nearly kills it because it will go to like 300rpm and then jump back up and then settle out. There has been only one instance where I started it and it jumped way up, and then died from being too of RPM's. I'm curious as if there's any way to avoid this or at least make the issue a little better. It's pretty annoying. If I wait like 10 minutes, it won't do this.
