whatever you want, beer, smoke, money.. all of the above

ive ------- looked at everything. I put stock injectors and a stock burn on the ecu this morning and it still doesnt run right. 2k miss and its dead after 4500. Almost every ------- part on the car is new. Someone with some real experience getting hondas running... i like to think that im smarter than the average bear, and im ------- clueless right now.

It can't be impossible man. Run down an organized list of the things you've replaced on the engine/wiring/ecu. It must be able to be solved somehow. If I wasn't out of the country, I'd give you a hand, but unfortunately, my cost would be a round trip plane ticket from Colombia...

This isn't a VW, it's a generally easy to fix Honda.

List everything, and it can be solved.

hmmm,

engine is a B18A: head had bent valves so i replaced it with a b18b one, and intake manifold

new dizzy
plug wires
plugs
hg
valve cover gasket
timing belt/tensioner
front pump seal
im gasket
comp #s are 185 across the board
when i do leakdown, i hear air coming out of the other three spark plug holes? thats odd, engine may not have been in the right position, i lined it up with the mark on the crank pulley but it may not have been on the compression stroke now that i think about it.
i just switched to stock injectors and a stock burn b18b map off of xenocrons website. This would eliminate the possibility of a bad basemap/injectors. If anyone has a stock obd1 integra ecu, that would be nice to test. I suppose i could still have a bad chip. Has happened before.
I pulled each of the plug wires while holding it at the 2k missfire, each one makes the engine missfire more.
Every sensor is matched to the correct wire on the harness
what else, i dont know. Ive worked on it every day off i had for the past few months with little to no progress.

Yea if you arent throwing any codes, the sensors/wiring should be fine... I cant think of anything simple off the top of my head other than grounds

sounds like a plan. This head supposedly came off a running integra, but it sat for awhile. Thanks for the insight

i just pulled the vc to see what were talking about.. i already changed those seals, came in the valve cover kit. I thought it was something like the d series tubes that would pull out from the bottom and there was a seal down there or something, but the tube is cast into the head on a b series.

any other suggestions? The plugs are black from running wayyyy rich on the basemap that my version of crome made for some reason. That would burn off after a few minutes of running correctly right? Im gonna get some new plugs tomorrow morning and see if that does anything. I love dumping money into this car

Did you ever change your fuel filter? It could be possible it's almost clogged, but if this was the case, it would probably have white plugs from lack of fuel....
If it's the stock fuel pump you might want to test the flow or try a different one.

So is the dizzy brand new or a different one? First off, I would guess that is the problem, but then you say it's new...

The plugs. Are they factory spec with the correct gap? They're probably black b/c the engine just sputters for a few seconds and never heats them enough to make them clean.

Have you made sure all of your grounds are good, tight, and the connection to the body are free of paint?

If that stuff is good, I don't see what else it could be other than your ECU. Try swapping in a stock one. It's always good to have an extra one for these types of issues.

Good luck.

fuel filter is new

distributor is brand new, same with cap, rotor, and plug wires

plugs are ngk 7s at a stock gap

the engine starts and idles pretty good, just has a miss at 1.5-2k and doesnt really rev up past 4500

grounds are good

swapped a working computer before, but not after switching to the stock injectors. Still could be a bad chip (had the same one in the known working ecu)

danronian

Yeah, it sounds like your chip is what is wrong. And with a stock ecu, and big injectors, it will barely run.

Try the stock injectors, and a known working stock ecu, or with a new chip. Doesnt sound like anything else can stop this motor from working for you.
