Does the 2002 Sentra have 2 catalytic converters?

Hello everyone and thanks for your time. For a couple years now I've been having issues keeping my car running if its colder than say 30ish. If its down in the teens like it has been lately I have to keep it at around 2000rpm to keep it from dying. Holding my foot on the gas the whole time I drive even when I hit a light. Within bout 10 min of driving it runs great. All summer it runs great as well. I might add it always starts right up cold unhappy or not but when its cold it struggles to stay running. Any points I can go after? Hopefuly a cheap and easy fix but sometimes I'm not that lucky... Have a good one amd thanks again

The one that I can see in there is stainless woven tightly. Is that stock? And if so will it be a big deal getting one that's not woven s.s.? Thanks in advance n thanks

I put a head gasket on my sentra,everything seems fine,it runs fine when its in park and you accelerate but when you drive it it has no power,I changed the spark plugs ,the compression checked ok,when I visually check the fire it seems more of a yellow color instead of blue. Does anyone have any suggestions? Thanks

And is the wiring diagram the same for both? And where can I get one? I prefer texts over emails, but not a prohibitive issue. Thanks for your help.

at first it was stuck in park and windows wouldn't go up . replaced a fuse so why my car won't change gears?

It will roll down but won't roll up

i replaced the cat and all four o2 sensors and i drove over 100 miles going through the reset cycles and still the computer reading not ready.

while driving car loses power even with foot on gas petal it dont want to accelerate the rpm on dashboard dont even move also it jerks and turns off sometimes. I did a tune up and still runs the same. What could be wrong.
