i was getting off the interstate when my SES light came on. so i stopped by autozoneon the way home to have to code read...it was a misfire on cylinder 6.a while ago my cat. started making a rattling noise, which probably means its time for a new one.

my question is this : iwas reading on a differnt forum and saw this,

"when my cat died it didnt say anything about the exhaust, it just kept saying that cylinder 6 was misfiring. check the cat, that could be the source of it all."...........so i was wondering what i should do. would it most likely be the the plugs and wires or the cat.?

 

anybody?....i kinda need help, this is my only car and i dont want to drive it more than i need to until i get this fixed.
any suggestions would help. thank you

 

What year car? 96 & up will set codes when cat goes bad.

 

sorry...its a 99'
ummm...so should i try replacing the cat first to see what happens?

 

I would, especially if you need a new one anyway..

 

If the cat code is not set, take a look at the #1 plug & wire first, cheaper & faster than a new cat. If the cat efficiency code is set, change out the cat first.

 

whats the cat code?....the code i had said it was a cylinder 6 misfire.

 

P0420 to P0430

 

no, i think it was like p03301 or something like that.

 

Too many digit,s but close to a misfire for cyl #1
