Hey everyone, so My 95 5.8 has a sticking/failing EGR, I haven't noticed and significant drop in my MPG, and I know this has been an issue since I bought the truck just over a year ago. The check engine light comes on either right away, or as long as 10 minutes into the drive, I pulled the codes on the EEC IV self test and it came up as my EGR not closing, or Code 332. I've replaced the sensor (the thing the harness plugs into ontop of the EGR with 3 nuts on 3 studs) hoping that that was the issue, it was not. So the Main question here is, How do I get this EGR Valve off for replacement? I would steal the one off of my parts truck, and I've already tried, but I'm lost, I removed the bolt/nuts holding it to the Throttle body, (from what I remember I could only find 2) What else needs to be removed? I can't find anything anywhere about a 5.8 EGR removal. Please Help Me!!!

 

Code 332: EGR valve opening not detected.

Before you start twisting bolts...make sure the vacuum circuit is intact.

The PCM modulates the EGR Valve Regulator (EVR) to control the EGR under light load/cruising conditions.

A simple test is to apply full manifold vacuum to the EGR (jumper a piece of vacuum line to the EGR while the engine is running), visually inspect to verify the EGR is opening. If not, you know the EGR is stuck closed. If it opens then you can trace down the normal vacuum route (Manifold vacuum tree/EVR/EGR valve).

 

Okay awesome, I will start looking in just a few minutes! Thanks!
