Don't use brake clean on either your MAF sensor or EGR valve. Electrical parts cleaner or MAF specific cleaner here. I wouldn't recommend using brake clean on the EGR either. For the EGR valve, the same stuff can be used as what is used on the MAF or some sensor safe carbon cleaner.

As far as the EGR gasket goes, if the screen plugs up, it would end up tripping an insufficient EGR flow code which wouldn't cause any real driveability problems. If a chunk of carbon gets stuck in the valve itself, it can cause some bad things to happen.

 

The link to the MAF cleaning doesn't work anymore

 

Could someone plz give a link to the MAF cleaner site that works?

 

I don't have a site link but should be stuff on you tube. To be honest if you just follow the directions on the can of MAF cleaner you should be fine.

 

Thanks for your response. I'm a newby and had missed the tech write-up. Found that and the world is wonderful. I am going to really enjoy being a member of this forum. Thanks a bunch................

 

Figured it would be better to add to this discussion instead of starting new thread. I'm trying to clean out the EGR passages as well as the valve. The one that really needs cleaned is on the right, correct? I haven't found a brush flexible enough to get in there, so I'm trying the bicycle brake cable/drill trick. Just not sure how long my cable should be to clean entire passage. I did seem to have a blockage just a few inches in, while poking around with the cable by hand. So I'm sure there's a lot of buildup in there. Any extra advice would be appreciated.
