Egr vacuum modulator

2002 Toyota Tacoma 2.7L
Noticed my truck lagging no power when driving wouldn’t go over 2500 rpm’s and noticed a blow by coming from under hood. Got home noticed the egr vacuum modulator was melted, got a new open one from Toyota put it on and still didn’t run right and noticed after just running a mile down the road the niple on the bottom was starting to melt. What would cause such a thing is my egr bad? Or sensor? Please help

 

Codes?

tht Egr pipe gets hot
Melted some of my newly installed thin vacuum lines

 

miles?
...you ever tried to clean the egr/pcv port on intake?

CC this should be right up your ally.

good chance its carboned up those ports that go into back of intake plenum...

the egr opening and/or the pcv is all carboned up...

you should give him a link to how you cleaned yours....

 

Sadly
I did everything BUT clean that egr
New vacuum hoses
Now I have another project

looks simple enough
Need 2 gaskets/brake cleaner

My major ‘cleaning’ job was TB/IAC/intake manifold/plenum

 

My intake was clean and egr as well. What ended up being my problem was poor exhaust pressure front cat was clogged due to failure which was raising exhaust temperatures and overheating egr. Replaced cats and muffler. Runs perfect.
Hope this helps anyone else that might have the problem.

 

No Crap????

how close is that melted Egr nipple away from the CAT?
How did u determine a clogged cat?
Way high miles?

Interested….
