I don't know whts the problem in your case. The low pick in the beginning is quite common, for that you need to frequently tune it on perfect settings thts it.

Maybe you should try the following.

1. Get the throttle body serviced.
2. Change the plugs
3. Get your CNG kit fully serviced and also the cylinder if possible.
4. Oil change along with all the filters
