hey i need to know what to call this sensor because im gonna run to autozone and see how much they cost. its the towards the top of the hood on the throttle body. my idle is all screwy and that seems to be the problem. if anyone knows the approx. costs right off hand that would be great too. thanks.

 

MAP sensor, and no idea.

 

The one on top of the throttle body is the map sensor but I dont think thats your problem. Your problem might be the TPS sensor which is on the back side towards the firewall of your car. Dont know how much it costs new either

 

you can adjust your tps sensor. do you have cel??

 

Nvm I'm retarded.

 

i dont have a CEL. the only thing is surging idle from 1k to 2k non stop. like that whether it is warm or not.

 

Vacuum leak! Check all your hoses!

 

no sir. checked 3 times now. unless there is sumthing i missed SOMEHOW but i doubt i could of. we did an engine replacement, the engine ran fine in donor car, but we used non running cars tb cause the other engine didnthave it. so i figure that may be the problem

 

You can test them both so, just test them.

 

im not sure how to do that. today im gonna pick up a tb from the boneyard and ill just try it out tommorow i guess. ill see if it works.

 

its your fast idle thermal valve...do a search theres tons of info on it. it's a common problem on hondas.

TPS sensors hardly ever go bad, same with map sensors.

 

check your IACV thats what mine did it went bad. take it off and clean it and make sure the O ring is still there and in good condition.

 

if the iacv is the one on top, i jusyt replaced it and put a new o ring in. it was fine. something else is wrong. maybe another sensor im just gonna get a whole tb.

 

did you not just see my post???, its your ****** fitv, don't replace anything. just take it off and screw the ****** plunger back in.

 

i need a diagram to understand. for real. where can i find one?

 

do a search for FITV or fast idle thermal valve, there are tons and tons of writeups about it

 

ok i found some more info thanks for the help im gonna try tightening that screw tommorow and if that doesnt work im gonna scrape up some cash for carb cleaner to being unemployed

 

hows she runnin?

 

idle problem is better but not fixed. how far do i screw the fitv in? i screwed it until i could see those holes on the inside. i didnt want to force it. but now it idles from 1k to 1.5 k vs the 1k-2k its barely noticeable. i cleaned the screen on the iacv too. im gonna put a new tb gasket in and see if the problem will get solved

 

screw it all the way down

 

ok ima try that tommorow then and see if the problem is all the way solved. because now that i kicked my muffler off for being gay yesterday its super loud and noticeable.
