EGR vaccume issues

[comanche32]

I cleaned my iac today and noticed that the hose that goes from the plastic t to the metal egr was blocked off. so i plugged it in when i did the truck revved really high and wouldnt stop.

so i unplugged it and blocked the line again and it returned to normal. does this mean the egr is bad

You may want to post a picture because the I.A.C. is not connected to the EGR transducer or valve. Here's a link to some common sensors. http://www.lunghd.com/Tech_Articles/Eng ... ostics.htm

 

Reading your post again I realize you didn't say they were connected. If your EGR valve is not closing then you need a new one. They're easy to replace. Look through the above link to get more details. Good luck!

yeah I know there not connected I meant I was looking the engine over after I got done ceaning the IAC. and I noticed the vaccume line was blocked off with a bolt and when I hooked it up to the egr it revved real high so I unkooked it and it ran fine.
