here is the problem, i have and vtec 95 prelude and and have had water ran into the engine and the engine is broke, i bought a new engine to replace it, it's also vtec h22a1, when i finish every thing, and turn on the engine, you know when you turn the engine on, the rpm at first it high then it go low right, that it the problem when the rpm go low, the engine turn off and i couldn't drive like that, if i want to drive i have to keep the foot on the gas paddle all the time which i could do but it too dangerous, i really need your suggestion
thank

 

possibly a vacumm leak, check your vacumm lines.

and for god's sake try to post in english.

 

I'll second that on the english thing!!

 

did you do a compression test before you bought the engine? You coul;d have bent vavles in there...

 

after re-reading that for the 4th time, i think i understand it ( should i be scared ).

Forget the vacumm line idea.

 

I could understand such an English as it's not my native language

Did you adjust your valves? Cleaning IAC also helps.
