First question. On the PCV system you usually change the PCV valve (which I've done), but on the other valve cover is the air inlet for the PCV system right? There's the tube running off the intake and into a 90° grommet into the valve cover. My question is, has anyone had any problems with the intake being clogged? Should I be cleaning this out, or replacing the grommet?

Second question. A while back, there was a post on adjusting the TPS, and it also talked about adjusting the minimum idle. I know the procedure for adjusting the TPS, but I'm a little confused on the minimum idle thing. Is the minimum idle just something you do before adjusting the TPS, but is entirely separate? You adjust for minimum idle and then when everything's hooked back up normally you do the TPS adjustment right?

Thanks. Can I assume those values are valid for the 2.8?

Also, anyone wanna have a go with the PCV question?

 

My tube ws clean when I pulled the heads of teh 2.8. The grommet is pretty easy to remove & put back on, I did it when I painted teh valve covers (or did I just tape it off, I forget )

 

could be wrong on this but could u not just take it out and put a air breather in it.

 

Actually, that's an excellent idea!

 

weird thing. when I put a breather on my car, my SES light would come on, but as soon as I took it out and put everything back the way it belonged the light went out...why???

 

check out the tech section of sethirdgen.org, Don't like the forum over there but the tech stuff is easier to follow.

So is 450 rpm the value for the V6 also, or it is something different? Or should I just go as low and as close to 450 without stalling?
