Car: Stock 1994 Accord EX

I'm seeing two problems. Sometimes, the car will just idle extremely high 1900-2300rpms. Othertimes, it will fluctuate between 1200-1500 back and forth as if i was trying to taunt someone to race me

I don't know exactly what would cause this...could it be something to do with the throttle position sensor? Any other things you guys would suggest is the problem?

Other minor problems: I don't know if this is related but the cruise control is off when you set the speed. After setting it at a certain speed, it will always go about 3mph faster than that.

throwing any codes?

 

Vaccuum leak maybe?

 

Does the idle fluctuate when the car is cold? It could be the IAV, FICV, or perhaps a sensor as you mentioned...

 

The check engine light isn't on.

And this problem is consistent whether the car is cold or warm.

Where could i check for vacuum leaks?

Another odd thing I noticed is even though the car is stock, at low rpms and accelerating, for a second, you hear a loud sucking noise as if i had cold air intake or something. So maybe it IS a leak?

 

Yeah, it's likely a leak. Check your vacuum hoses on your intake manifold first...

 

Sure enough, I went down during lunch to check them and the problem is the hose that goes from the manifold to the valve cover. Only problem though is that it's not a loose hose, the whole metal braket that's suppose to be stuck on the manifold is broken off. I'm thinking I can use JB weld or something to keep it on there?

 

JB Weld 0WnZ!

 

Yea, sure beats buying a new valve cover.

 

Newbie question: What is a TPS? Thanks.
