hi im curently having an idle problem with my engin .. rpm far from stable going up and down from 250rpm to 1000rpm and back down on idle ... i have a 1.5 1990 intake on a si v-tec engine i cannot give you the exact modle of the engin never checked ... first i checked the tps sensor .. witch was broken ... and the trotle body was some what damaged ... replaced it with one of my old civic dx 1.5 trotle witch worked perfecly on that car ... after i instaled the new trottle body the car stablised at 2300rpm ... hade to clog the side vacume hose with a bolt for the idle to be at a normal idle rpm... (side vacume hose ... dont know the real name for it .. but in picture its in the blue circle ...) it ran good for about an hour and a half then started to have the same problem again ... any ideas ? (i have tried lowering the idle with no sucsses) car used to work great with the same trottle body before the tps sensor broke ...

 

Are you actually serious? This is probably the most hilarious thread I have ever read. I'm loving that diagram, it's so....concise?

 

search cleaning iacv/eacv.

that should at least give you somewhere to start.
