I need to go through my vacuum hoses, but has anyone had this problem?

After I finally got my timing belt fixed (or at least i hope!) my car started having a weird problem.

Whenever I drive and let off the gas, the rev's will stay around 2.2k until I come to a complete stop....then it will drop back down. My TPS voltage is 0 during this, according to my VAFC, so i don't believe it's the TPS.

Anyone have any ideas off the top of their heads?

 

I remember that used to happen when I used the factory Civic ECU to temporarily run the engine. Something is not right with your setup.. What ECU you using?

 

make sure your throttle cable isnt to tight. If you over tighten it, it tends to do that. Check all vacuum hoses to the back of the intake manny and trace them back.

 

I'm using the P13.

I actually had a prob w/ the MAP sensor the other night; a vacuum line cracked. I'll double check the hoses back there.

 

See you already answering your own questions..

 

Haha, well I already fixed that problem and the symptoms I was having went away. The problems i'm having now are not like the ones normally associated w/ a problem w/ the MAP sensor.

I'll be checkin the hoses anyways. I can't think of anything that would cause it to raise until the speed came down....

 

Well it's screwed up even more now.......

It no longer drops to normal idle when I come to a stop; it stays at ~2.2k all the time at idle. And when the motor is warming up, it stays at ~3.2k.

The vacuum hoses going to the MAP sensor were fine, and the MAP is new. The only thing I know of that needs to be fixed next is a kinda bad exhaust leak between the top and bottom half of the header.

Also, I got my wideband installed, and it's showing full lean unless I floor it, and then it shows full rich. SOMETHING's up!

Blah.
