comanche32 Posted September 2, 2011 Share Posted September 2, 2011 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 Link to comment Share on other sites More sharing options...
MJRemi Posted September 3, 2011 Share Posted September 3, 2011 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!

comanche32 Posted September 3, 2011 Author Share Posted September 3, 2011 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.
