04 EXT 4.2 w/ 194K
Pretty sure I have a clogged cat. Monday on the way to work it was bogging down and died. Couldnt make it up a hill, but never illuminated the SES light. I got her home and took my silverado to work. Monday when i got home I cleaned the TB, installed a new Air filter, and fixed an air hose nipple on the resonator. Started her up and hardly any exhaust pressure, and then the SES lit up and Reduced power light. I checked the Fuel pressure, and read 54psi.
Well after a few repeated attempts the engine finally revved about 2k, and kinda drove ok. The reduced power light turned off, but SES still on.
Well today while waiting on my buddy to come read the code I decided to drill a hole in front of the Cat. The SES light immediately went off. Makes me think it was definitely an O2 sensor code do to a clogged Cat.
My question is, Would the SES light really go off that soon if it was an O2 Sensor code? I know some codes take many miles and proper speed to be reset.
I'll be replacing or gutting the Cat this weekend.
Thanks!
