Cadillac Catera and Cimarron Forum Discussion, Catalytic Converters condition? in Past Cadillac Vehicle Discussion; 2000 Sport with 154k miles!
I did temperature test on Catalytic Converters.
before cat. - max -270f
They could be clogged, I know mine are and my acceleration is complete crap until I can afford to get the cats cut off and the two new ones I have installed, also is the CEL coming on while driving? could indicate o2 sensors need a cleaning or new ones altogether
Well I don't have no check engine light and got me new o2 sensors. I just not happy with preformens. My girlfriend suv 2006 Pontiac torrent mush quicker on picking up speed and at work I'm driving 2012 ford escape- way faster. My moms Honda fit with 1,4L less torque and to compare with Catera that have 3L with 200 torque feel like its not going no where
