[QUOTE="Alex D, post: 28151, member: 11090"] Hello, im new to this forum i have a 2011 equinox lt with the 2.4 and its fwd, it has 154,900 miles on it. Nice little suv Yesterday driving home, the car just kind of dropped in power now it was sputtering some but at first i thought maybe it was a engine miss maybe bad plug, bad injector, but then it didnt really wanna go at all. I mean it would bogg out at a traffic light if i didnt shift it into neutral. And when it did go, it would sound like it was clogged like the enging would sound super muffled, and then itd go back to normal power randomly. Now I had changed both 02 sensors recently for almost the same issue. Down on power and sputtering, had to shift into neutral at lights to avoid bogging out. and the previous owner had changed the throttle body once. It gave the P0420 code when I changed the o2 sensors originally. Is it more than likely it is the cat. Because at this point I can't think of anything else. If so, is there one of the 2 that is more likely to have gone bad? I've purchased both change but it's also 100 out here today and if I can just fix one and be good til the heat wave moves on I will lol. Thank you for your time . Alex [/QUOTE]
