ight now my question is when i'm jus sittin in neutral my rpms surge/pulse/up and down not alot usually only surges up n down like sometimes 300 rpms and sometimes a lil more like 500 rpms any idea wat it could be any help greatly appreciated

 

it surges to 500 rpms or it surges 500 over what it normally idles at?

 

hmm are you in your driveway, are you at a light? does your fan turn on do you have your ac on? and how can you tell your at 300 rpm shouldnt your idle be at like 7-800?

 

Vacuum leak or FITV.

He meant that it the motor surges between 300-500 rpms above idle.

thank you Shane like he said my idle is roughly 700-800 but sometimes it will surge back and forth from 700 up to like 1000 or sometimes a little more

 

it's all the time whenever i'm not in gear it happens

Then definitely try checking for vacuum leaks, and if you have a FITV, clean that as well.

FITV??

 

Fast idle thermo valve. According to my manual, it comes on CRV and Integra auto's. It must be available on more JDM setups, because my swap had one on it.

you got a check engine light on?

 

And just so you know, the FITV is bolted to the bottom of the TB (throttle body). What motor do you have anyway?

its on most cars, its what makes them idle higher when its cold out, to help the motor warm up faster


it will either be on the back of the intake manifold, or on the throttle body

 

i have a d15b block with a d16y8 head mini me setup with aem cam and adj. cam gear


now theres also another prob kinda hard to explain but i'll try my best ....

now when i'm driving down the road and i'm in any gear usually low in the gear it feels like the motor starts to pick up then it feels like it jus cuts out not all the way but most of it even tho i'm still pushing on the gas and then once it picks up a lil bit it will start to accel. as hard as i'm pushing it ....

my first thought was the lil flap stickin in the trottle body and then i also thought maybe it's not gettin enough fuel or to much air like maybe it's a sensor like when it's jus sitting and u look under the hood it sounds like it's suckin in a shitload of air

 

check engline light is on throwin o2 sensor code but it has been throwin that for awhile and before i never had the problems like i'm having while it was throwin it

That's funny. My manual said that it only comes on the CRV's and Teg's, but I kinda had a feeling it wasn't correct. Of course it's a Haynes. I actaully like the Haynes, but don't think it is 100% accurate.
