Hey guys. I recently did a tune up on my SC300 2JZGE and replaced the spark plugs and spark plug wires. Everything went smooth but when it came time to start it up the car starts fine but does not idol properly. It revs up and down on its own like it wants to die back n fourth to 2000 RPM's. What do you guys think the problem is? I've checked all my connections and they are correct. But there is a stray vaccum line coming from the back left of the engine bay looking like some kind of vaccum diaphram with electrical connectors on it. ALSO, the car does not rev up when I hit the gas!

There are like a million vac hoses there. if you post a picture most of us could tell you what it is and where it goes.

also, when you have the hood open. if you look up towards the front of the hood, there will be a sticker which has all the vacuum lines labeled on it. it is very helpful.

did you figure it out? i havent had a chance to go see exactly where that goes yet.
Im pretty sure it goes somewhere in that rats nest of egr hoses.

No we have not yet found where it goes. Please if anyone can look unde their hood and tell us where this line actually connects would be amazing. Thanks guys.

Lol I have just about the same problem right now, hopefully someone can find out where to put this hose.

That vacuum hose doesn't seem too long at that point so can't you just trace it to an exposed nipple?

A trip to the stealer will cost you hundred $$$ easy.
Buy an inexpensive digital camera, post photos, and someone can probably diagnose it.
Problem solved, ....and as a plus, now you own a nice camera!
