As you may know, I got my truck back from the shop a little over a month ago. Ever since then it's been one problem after another...

First it was the TPS sensor.
Then it was the coil packs.
Then it was the knock sensor... Which I replaced last night.

Here's a picture of the new knock sensor compared to the stock #2 knock sensor. The ceramic connector fell apart in my hand when I went to remove it.



NOW it's a ****** vacuum leak.

My best guess is that when I put the EGR valve back on, I didn't seal it completely. So, that's the first thing I'm gonna check.

Update later.


Any suggestions?

 

That's gotta be the "nastiest" knock sensor I have seen.

Vacuum leaks can be troublesome to find. Since you took off your intake manifold to change the knock sensor, any chance your gaskets are not seated properly? Can you determine what bank your leak is on?

Obviously I would start to look at the items you messed with first.

 

Yea, when I saw it my jaw hit the ground.

I dunno. I think I'm probably just gonna take the intake off again and redo everything... Probably won't be today though.

 

did u do leak test? leaking is nasty. it will be long hour work.

 

Man, when it rains it pours huh? That knock sensor looks like it needs flood insurance!

 

friggin vacuum leaks, dadgum engines are way too sensitive anymore.

 

Ok... What the hell is this and why would the wire connecting to it be unplugged?

 

That is your fuel pressure regulator, and if by "wire" you mean vacuum hose, then by golly you just found your vacuum leak. Other problems like rich idle condition will be solved by reconnecting this tube as well.

 

Yup. Plugged the hose back in and it ran fine after I reset the computer. And yea... I was trying to add sarcasm with the picture and caption.

Now I gotta replace the #1 knock sensor.

 

Damn... Guess nobody works on their own **** anymore...
