Is there a way to tell if a cat is clogged on a 00 civic without having to take it all apart. My car has had a loss of power for a while and checked everything else. It just seems sluggish and doesnt want to accelerate quickly anymore. I just dont want to go through the hassle of taking the exhaust apart as the bolts are always rusted.

 

what all have you checked? b/c I have never head of a clogged cat...

 

hook up a vacum guage and see what its reading... a stock engine should be like 18hg or in that area of vacum.... if you have a clogged exhaust it will read kinda like 8 hg or so.... also that reading could mean retarted intake timing...

unbolt the down pipe and take it for a spin and see if your power is back. If it is then yes u have a clogged cat

 

new air filter, new plugs, wires are still good, changed oil, new pcv valve, new alternator, battery is good, new timing belt a while back, timing is on, new water pump.
