If your Honda is naturally aspirated/carbureted, then your only problem is the fact that the diaphragm that squirts gas into the venturis is not operating. Maybe just need to replace said diaphragm or maybe just an adjustment to make it squirt sooner is all it may need. This initial gasoline squirt is what keeps the engine from dieing when you stomp the throttle. Understood?

Even the best kept vehicle can have an EGR problem. Makes no difference what else you do to it to TRY to make it run better, until you replace the Exhaust Gases Recirculation valve, you'll always have the problem. Replace the EGR, no more problem.

Is the fuel pressure ok under a load? Is the MAP sensor good? Does it have a good vacuum signal from the engine? Is the timing belt set up properly, it may have jumped a tooth (should be replaced about every 60,000 miles). Is the exhaust free flowing with not excess back pressure?

Hi, I hope I can help you, but need some info.
1.Did you replace the actual thermostat or just the housing ?( your statement says "just put in thermostat housing". If the car has no thermostat, the coolant never has a chance to stay in the radiator long enough to cool down and eventually boil over.
2. If the thermostat was replaced, check to make sure the correct temperature rated thermostat was installed and it was not installed upside down.
3. You mentioned "water started boiling". Was the cooling system filled only with water? Using just water only, and not an actual engine coolant, should never be done, as water will reach a boiling point faster than a coolant and will also corrode the inside metallic parts of the cooling system.
4. Is there any visible signs of leaks in the cooling system when it's running? Any puddles forming under the car? If yes, the leaks need to be addressed before trying to repair anything else in the system. I hope this helps, and please write back, as I will check back for any updates you may have written in on this.

Try doing an ohms test on your fuel injectors. Sounds like 1 or 2 could be bad.
