engine idel up and down on b16a2 engine.
use brake dust cleaner to clean ivac ??do i need to take ivac off or just unplug the hoses?thanks

 

could possibly be your throttle body control sensor

 

to the op, i have sorta the same problem.. is yours always idling up and down?

 

The hoses that attach to it are coolant hoses, so no, don't take them off.

A hunting idle is generally the symptom of a vacuum leak.

 

Might want to check your tps sensor also..... Just a thought

 

take it off and clean it with throttle body cleaner and see if it works....if not.... check vacuum leak

 

thats what i ment lol had a brain fart. this is the same prob my bud had. do the tps sensor

As in, the TPS sensor was bad altogether? Or just misadjusted?

 

Yeah, my B16A2 also idles weird. Sometimes at a light i turn on the AC just to up the rpms. I just replaced the tps by means of swapping the entire throttle body. whats the best way of tracking down the vacuum leak?

How mine idles is... 400-600rpm dip down bounce when the extra gas is given back up to 800 then to 600 dip repeat.

how does one clean the IVAC?

 

i have heard use brake dust cleaner would help ^^^^^^^^^^^^^^^^

 

try cleaning its surface and sensor and if all else fails replace it.

ive got a weird idle too..... but its the crower stgII cams

 

im currently having same problem with my 00 civic si its got a greddy turbo kit running 7psi but the check engine light came on did a scan came up code 13 which is atomospheric pressure sensor. i was told it was the map sensor. but it also idles at like 400 to 1200 rpms

 

same prob. here, i just droped a b16a2 in my eg sun. night and its jumping from 1000-1500 and throwing the ivac, map cels

 

Me too,

But my engine is a D15Y7

Does anyone know if there is a tps sensor on the throttle

 

damn everyone has this problem.. including me and its driving me nuts

 

Holy crap me too and ive checked the CEL and i get the MAP censor And IACV and i haven't cleaned that but ima try tomorrow!


I also have a lil pipe coming out of the Fuel Filter and i dont know what i connects too


ohh i have a d15b Vtec

 

I have cleaned mine and have no more problem.

One thing I notice is I have to make sure all the parts seal good before putting in back. I put silicon to seal the parts is because the rubber that does the sealing get too old and broke.

 

I had this problem with my 93 civic dx B15b7 and i cleaned the FITV and now it idles just fine

 

I have this problem with a d16y8 but the funny thing is when i use the obd2 ecu it dosen't do it but when i use a p05 it does it. I have it in a 95 si, its wierd.

 

so to clean it you just take off the entire throttle body and clean everything with throttle body cleaner or brake cleaner. i will try this tomorrow and see what happens. i really dont want to buy another part if i dont have to.

 

if you clean it with carb clean or brake clean, you need to spray some lube in afterwards because the cleaner will dry up the rubber piece inside

 

IACV FTW most of the time on erratic B series idle. I had to replcae mine after i got rid of all the vacuum leaks and that was the only thing left.

 

Erratic idle can also be caused by air trapped in the cooling system. So, in some cases, properly bleeding the cooling system can solve this type of idle problem.

 

is it possible for the coolant to leak into the TB?

 

Holy Thread revival!
