i have searched alot of things. i jus finished up my mpfi swap and go to hook up the vac lines for the map sensor and the purge thin on the firewall and i dont kno where to route them on the z6 im or fix my idle

 

did you use a z6 throttle body and manifold too??

 

yes i used the z6 complete intake mani and these are the only ones that arnt hooked up

 

damn you got pictures and everything!

on this one.. the black capped thing is basically the obd1 version of the soleniod on the fire wall. i see you took it off in the second pic
the vacuum port below it just cap it... or run it to the soleniod on the firewall


now in this one.. the black thing on the top of the throttle body is your new map sensor... just extend the wires to it
[/QUOTE]

 

On the first pic..That thing with the black top is your purge solenoid. Down underneath is your air temp sensor.

The second pic...Your MAP is on the manifold right on top of your throttlebody.

So don't use the MAP on the firewall use the one on the TB. Don't use the purge solenoid on the firewall either use the one that is pictured attached to the manifold.
EDITED>>Or not! either way is OK.

The last thing left on the firewall is your fast idle solenoid and I can't give you any info on this as I am not familar with the TB you have.

 

ok i hooked the map sensor to the one on the tb and i hooked the wire from the black cap thing hose to it and i still get a high idle and codes 3 and 5

 

some one please write back need to get car running again at normal idle speed

 

ttt

 

lets test this then.. plug the map sensor on the firewall back in... and run a vacuum hose to the manifold.. like the one on the back of the manifold. see what happens

cut the car off then lets pull the map sensor off the throttle body and check its seal to the throttle body. see what happens

well go from there

 

ok i did that. the seal is good and when i used the firewall map sensor connected to the port in the back it does the same thing also the purge solenoid hose was t'd there to.

 

Your idle... Do you have the IACV plugged in? (Round thing on back of manifold with two bolts)

If it is not plugged in then that is your idle problem.

Plug in the air intake temp sensor. (White plug in first pic by the bottom)

You need to get all the sensors plugged in.

MAP leave it on one or the other. Cap off the purge solenoid vacuum source. Also the purge line from the charcoal cannister to the throttle body(First pic..orange hose)

See what these do for you.

 

all my sensor are hooked up cept for the pcv valve. leave it on what other 1 the firewall or the throttle body? so everything from the cannister u want me to cap off?

 

For now, yes. Til we get it to idle right.

Choose one and stick with it. Personally I would use the one mounted to the IM.

You say the PCV is not hooked up? C'mon hook it up.

 

do u think my ivac could b stuck open?

 

not to thread jack but i am in the process of doing a z6 swap myself and i plan to leave the lower left vac. port hooked to the purge solenoid as it came from the factory and cap the one on top. is that correct?

 

u want me to leave it on the tb or what?

 

well this was taken earlier in the day when i had the 2 vacuum lines hooked up to the nipple on the back on the intake mani

I can find the connector for the map sensor, I just did a swap and was told i need to extend it from inside the dash? is this correct? Where in the dash? Thanks!
