Wonder if your timing belt slipped? Almost sounds like it is out of time a little bit. How many miles on car and last timing belt change? Another thought was a major vacuum leak some where. I once didn't push my oil dipstick all the way in and the engine barely ran. No back fire noises though.

 

picked up the car from a guys said the car had been sitting for 6 month car has 165k on it I will check out the timing belt tho I have been going through changing this out bit by bit but couldn’t figure this out for the life of me
