I am checking for Vac leaks and put my gauge on the side of the evap (if that is what it is called) that is disconnected and it will not hold pressure. The side that is disconnected goes to the charcoal canister. The side that is connected in the picture holds pressure and goes to the Throttle body. Is this correct or is it bad? Thank you Sandy
I do not have a CEL only a 1k rough idle.

 

That's the Evap canister purge solenoid. It should hold vacuum when de energized. There should also be a little arrow indicating direction, should be toward the throttle body.

 

The arrow says ENG and that side is going to the TB. So are you saying both sides should hold pressure and mine is bad?

 

Sounds to me like the valve is ok. The side you said goes to the engine is holding vacuum. It should release the vacuum when it is energized, so if there is no power to the valve you are good to go.

 

Pardon me cutting up your post

Then the solenoid is bad.

Just cap the nipple on the TB & see if your problem goes away if all above is correct.

Edit, looks like the pump is going to canister, sorry. No it won't hold vac there.

 

Thanks for the replies guys. It became a moot point as the nipple broke on the engine side of the solenoid as I was removing tubing. I got a new one as there was no repairing what happened. My rough idle seems to be better (going for a test drive now) but the idle is still high at about 1K+. I will post after the drive. Thanks again. Sandy

 

Well the rough idle is about 50% better but the idle is still about 1100. The search continues with some success. Thanks again guys. Sandy
