2000 Mercury EGR PROBLEM

[AutomotiveServWork]

Hey Guys thought I might have posted this question a few days ago but here I go. I work on cars & trucks on a daily basis and I have across of a 2000 Mercury Cougar with the 2.5 L engine that has a blown egr valve and I mean blown to the point of theres a hole in it. NOw im suspecting possibly a clogged catalytic but not sure. I was hopeing someone can chime on this. Customer is on a budget cars in great shape except for this problem. They replaced the EGR valve a week ago and it wouldint even make it one block before exploding again. I suspect catalytics anyone thinks differently let me know.

Any Codes?
Did you check the back pressure?

Sorry for the late response! Back pressure seems very high never checked codes yet.

CHECK the back pressure. Unplug the O2 in front of the main catalytic converter and plug in a pressure gauge. snap the throttle a few times and read the gauge. if you see over 3psi you got a clogged cat.

you haven't checked codes? are you mad!!! Thats like the first thing you should do lol

FYI On a 2000 cougar with a 2.5 there are 3 CATS, yes I did say 3 CATS, trust me i know cause i just had to have them um well i had them fixed there is one on each manifold then the one behind the final o2 sensor and this car has 4 of those. Just to replace the two on the manifolds just for parts at a parts store, the one in the rear next to the fire wall is almost $800.00 by itself and the front one by the radiator is almost $500.00 by itself. if you take it to a shop its going to run you over 2 grand. thats parts and labor and it might take at least 2 days to complete properly...if you live in the Louisville, KY area, give me a call 502-419-0940 or txt better yet and i can help you out on finding a place cheaper. Good luck buddy
