Like title says.....I have a b16 in the car...it's obd1 so all the vacuum lines and **** are on the manifold....just trying to figured out what the deal is....it should be idling at 600 i thought...any ideas would be great....hit me!!

 

fit valve might need the platic screw inside screwed back down. vacuum leak or one of the lines are ran wrong.

 

it's hard to tell which it is because it's so random and inconsistant...someone mentioned the eacv valve going bad....he claimed that sometimes it doesn't throw a code....where can I get a good diagram of how to run these vacuum lines? the chiltons manual I have kinda sucks

 

try opening up the flat side of the fit valve and screw the plastic screw back in and clean the iacv out with carb cleaner

 

ok i'm not too dumb about this stuff but what is the
fit valve?

 

check vacuum hoses, clean the iacv, screw the little plastic screw in on the fitv, then check your idle screw. If the doesnt fix it, pull the throttle body, and replace the gasket. If that doesn't work, pull the manifold, and replace that gasket. If that doesn't work, check the pcv valve.

I had the same problem with my b16 powered DA, and it was the throttle body gasket.

fast idle thermo valve....its under the throttle body
you have to remove the tb to get it off easy, and it would be a good time to replace the TB gasket

 

same here....got a new gasket on it......i'm pretty sure the hoses are run right, maybe one of the hoses are just bad like a hole is in it or something.........

i would check the PCV valve before replacing any gaskets

Sorry, all those suggestions are off the top of my head, and are not in order. But yes, check the pcv valve before spending money on gaskets

 

thanx guys i'll let you know

thats a good idea.make sure there are no rips in the hose and it sealed in the grommet right.

 

replaced pcv valve and still high idle.....

 

did you inspect the hose for rips or not being connected right?

 

i checked for holes or rips....no sign....I'm pretty sure they'v been run correctly....but not positive....maybe if someone could post a pic of they're engine bay, i could confirm if it's right or not....

 

perhaps my iacv is bad....i could change that out
