Default missfire,sputteringD16A6

The head gasket blew so I replaced that not adjusting the velves,so I dont disturbe them.Replaced head gasket,timing belt,distributor,cap rotor,plugs,wires,the basics.Set Tdc,set timing,replaced fuel pump.Go to start it ran great all day,the next day went for ride,2-3min,started to missfire,or sputter,the more I drive the worse it gets,so losing power as I drive it for long period of time.What the hell is going on,no codes nothing,checked everything,it looks good,seems like im runnin on two cylinders thoe.I checked the spark on wires there sparking good what the heck.It ran better,when it burned antifreeze.Would not adjusting the velves cause a missfire after head warms up.I dont no?I need help please.

so all the parts that were replaced were

headgasket
intake gasket
timing belt
distributor
rotor
plugs
wires
oil,oil filter
fuel pump
main relay
antifreeze ..................The reason I replaced the fuel pump because i thought wasn't getting enough fuel.

you might have gotten a bad distributor? bad igniter? bad coil? bad fuel pump? check your restrainer, make sure is not clogged, gap in spark plugs.

I kept on taking those distributors back thing that was it I got the whole unit.And you say restrainer meanin what sorry dont know what you mean.Explain please I need to know every possibility.To rule out every possibility for the head and engine sake.Hondas are tough and well made.There interference so if something aint right she will tell yah.If you meant restrainer on fuel pump looked good.

i guess you could just adjust the valves, it wouldnt hurt. But i dont think that would be it.
The only thing i can think of is you got a bad part, but if it was something wrong with the distributor it would throw a code. And they say they are interference engines but 80 percent of the time nothing will happen. And if something did happen it wouldnt just start cutting out after it warmed up, it would do it and be consistent.
Possibly do a compression test to see what it is just for the hell of it. To get more info.
Hope that might help lol

It is consistant everytime soon it warms up 1-3 mins then it happends.I think the compression supposed to be 185 right sohc ,what would the dangerous compression be for low compression and if so does that mean what.And what should I do then if its low say across 90,100,90,120,just for say if that numbers come up.What can I do then to resolve that.

sounds like the hg blew again. did you check the head and block for straightness? if not, you should always check these things when a head gasket blows. in the meantime i would rent a cooling system pressure tester. it will allow you to put positive pressure into the coolant system without having the car running. if you have a leaking hg then you will likely see coolant leaking into 1 or 2 adjoining cylinders

low numbers that don't have much variation to them could be related to timing. if you're a tooth off it could definitely cause low numbers across the board. however since you said it ran great at first and now doesn't, i don't believe timing is the issue.

a better test then this, aside from the one mentioned above, is a cylinder leakdown test. works in reverse of the above. you pressurize each cylinder individually and watch to see if air bubbles make there way into the coolant system and out the fill neck on the radiator.

yeah like he said, if you do a compression test and they are all low, that is most likely going to be the valves are out of adjustment, most likely if they are not making noise they are to tight. If you have a couple of cylinders that are lower then the rest then your head gasket is blown again.
You can get a block tester from napa it sits in the neck of the radiator and you run the car, if there are combustion gases coming through the coolant system the solevent in the tester will turn a color i think its blue or green, then you know your gasket is blown.

Re-do the timing belt! I've done about 10 engine/head swaps and its right right on the first try.

Once you know its right, if there's still a problem, do a compression test.

Do a "wet" compression test and see if the numbers come up,if engine was cooked rings could be bad.
