So I have a 2011 Honda insight 77,0000 miles and the ac is not blowing cold when idling and when driving it takes forever to get cold and sometimes it blows hot then cold again. I recently bought this car from carvana. The previous owner definitely knew something was up with the ac because they got a recharge before selling it to carvana the Carfax report shows. I checked the ac pressure and it was actually a little high and I noticed when attaching the gauge at first it was to hard because to much pressure was coming out and with it yellow die so I think it has been died previously looking to a leak. But the refridgerant was actually to high to it couldn't be a leak. After releasing enough to bring it down to normal levels I noticed my car likes to rev on its own in idle to a little and it feel rough when the ac is on. I dont know what it could be but I don't think it's a leak. Other issues I have been having are the gas mileage sucks! I've replaced the spark plugs and used fuel injector cleaner twice it's supposed to be getting 40/44 but it only gets 27. And when I first drive it in the mor ing after it's been sitting all night it jerks when I go to accelerate and it feels like I'm going like stop go stop go. But only does it once then drives fine the rest of the day. There are no codes and no lights on the dash at all.

It would really be best to make each question a separate topic.
I'm not familiar with hybrid AC systems, but assuming that the Insight's is more or less like a conventional setup (the rockauto.com parts list for it suggests that it is), are all radiator and condenser fans operational? What are your high and low system pressures? The only way you can know for sure how much refrigerant is in the system is to evacuate and recharge it.
As far as the gas mileage is concerned it would be a good idea to check codes (a pro-grade scan tool may be needed) and live data. Checking the usual suspects such as spark plugs and air filter wouldn't be a bad idea. However if that 11-year-old hybrid still has its original battery that may well be shot and the gasoline engine has to work harder to make up the difference. You're probably going to need a hybrid specialist to diagnose it.
Are you meaning the hybrid battery or the actual car battery? And I was able to check the freon level and it was over filled. So I emptied and filled back up. And is does seem to be doing better. But I'm worried it might have damaged other components having been over charged from the previous owners This is a used car. I have recently changed the spark plugs all but two unfortunately two of the coil pack bolts are stripped and I did purchase a socket set for stripped bolts just haven't had time to change them. And the fans do appear to be working.
That would be the hybrid battery making the engine work harder if it's weak. How did you check the freon level? There really is no way to accurately do that but if way off it would of course affect system pressures.
Just to verify, did you pull vacuum on the AC system before filling back up? Was it refilled with the proper amount of R134a by weight? Did you use pure R134a or did it contain sealer? To get an idea of what's going on we really need to know the high and low system pressures and the ambient temperature when they were measured.
I figured it out got some UV die and it is leaking out the compressor and one of the AC lines. Thankfully it's covered under carvanas warranty.
Check your fuel pump pressure with a mechanical gauge.
