when it happened it would only go about 30 mph when it bew the eger it took off like a rocket. The check engine light came on right before the egr blew apart but is now out

It is difficult to know if the cat is clogged even if you feel exhaust coming from the tail pipe. I would guess that either the egr lines are clogged and need to be decarbonized

If the cat is clogged though would you have good exhaust flow?

I am trying to figure out what caused the problem. It is the orginal part from ford. What would cause it to blow up like that? Cat clogged or lines maybe carboned up not my car it is a friends car trying to help him out. But hate to but a new EGR on and have that one blow up to. They do cost around $50 bucks and he don't have much money

it takes runnin' with the black tape for a couple of months to choke a catalytic converter~

you might check the operation of the EGR...it uses a computer signal to engage...it shunts exhaust gas into the intake plenum on deceleration and also when combustion temeperatures are getting to hot introduces expended fumes to reduce combustion temperature~....now if the computer were telling it to open at the wrong time because a vacuum line had fallen off...you might check for blockage in the tube that goes back to the intake plenum...may be almost totally fouled with carbon...use some brake cleaner on that~

Did you figure out the issue? I just bought the same year/make/model two days ago for a pretty substantial amount of money for it to leave me and my daughter on the side of the road 28 hours after purchasing. I have the same symptoms and replaced it once. Its sitting until I figure out the cause. Please help!!!

Yes one of your cats are clogged you have 3 2 on each bank and one under car. I just had this problem on my escape the inside of Bank 2 cat broke apart and clogged the one under the car the fix was to buy a new bank 2 cat and install it then i took the one under car off and dumped out the peices

After reading POLOCK2's post, I don't understand how blockage in the Bank 2 catalytic converter can cause the EGR valve to explode. The exhaust air pipe feeding the EGR valve connects to the upstream side of the Bank 1 catalytic converter. However, that seems to be exactly my problem. Any theories?
