2002 Nissan Altima reply to answer

I had asked a question last Thur 9/24 concerning
my Altima losing its HP I did receive a answer and I thank you, I could not respond earlier because I was
on a scheduled vacation and I have just returned.I see in your answer to my question you had asked if my check engine light was on? The answer is yes. And has been for some time.I been reading a lot of post concerning this model Altima and all of the trouble with there catalytic converters. Prire to
my problem with lose of HP the car would on occasion smoke when first started. I also see there was a recall on this model car back in 2003 but I cant find out what was exactly was done to correct the problems with the pre cad burning up and being sucked up into the exhaust manifold and causing engine problems, I appreciate your answer to my question but I believe this problem may be a more serious problem just from reading the hundreds of people experiencing the same problems I am once again thanks.
