P1449 came one last week cleared it and came back on

you need a repair book on that car so you can look up the codes or call Honda and see if they will give you the codes and tell you what is wrong is the car even running good you can also take it to auto that has a reader they can put it on and they can tell you what they mean.

Hi:

The P1600 code is usually a IMA fault, and the P1449 code is a battery deviation fault.
Both are usually early warning of some sort of hybrid battery issues.
You need to have a system tech give the hybrid system a good look over, but most likely your IMA battery pack is most likely suspect

P1600 IMA system malfunction. A P1600 code is a generic code that is set in the engine computer to tell you that there is a Hybrid system problem. In order to find out what is wrong with the Hybrid system, you will need to take the vehicle to a Honda dealer so that they can read the code in that system.
P1449 Battery module,battery module deterioration, battery module overheating, battery cell overheating. Either way you need to take the car to a Honda dealership to find out the actual cause of the P1600 and replace teh battery module

You need the system scanned by the dealer for stored fault codes.

misfire can be caused by your fuel injectors also

You should have it checked by a qualified tech. Auto zone dont do diagnostic repairs, they can only give you trouble codes.

your clutch may be shot(the clear fluid was most likely from a hydrulic assist line)i do believe you have a hydrulec clutch

there may be a software update for the powertrain control module for mis-fire monitor. check with your local dealer. but if thats not the case,these engines are known at least in my experience of having the heads crack between the valves and cause mild mis-fires. try compression testing all the cylinders and performing a leakdown test on them as well.
