Ok, i have a 98 civic ex coupe and I have a check engine light, had it checked out and its throwing a code for cat convtr..........i am curious whether i can get an aftermarket cat convtr and solve the problem passing emissions?........

It could be the cat. But it is the secondary O2 sensor that is telling the computer that the cat is bad.

What I am saying is it could be the secondary O2 sensor.

It is cheaper than a cat.

Also check with your H dealer some emissions related components might be covered under warranty.

Not likely, if it has a p0420 it probably has a bad cat.

8 years or 80000 miles.

 

yes it threw a p0420 code............so can i pass emissions by getting an aftermarket cat like the one above on ebay?........rather spend $50-$100 on aftermarket one that can pass emissions vs OEM for an arm and leg.

We haven't had any luck with a/m cats, they dont seem to last very long. But i've heard from others that some work well, haven't heard a brand name though.

 

Ok, got a deal from my mechanic......got one that can pass emissions for $235 installed. Sounds good to me

but on the downside, i did lots of maintainence to the car.

rotors needed to be replaced (brembo) $150
brake pads $105
wheel bearing ($50 each) $100
hub $150
cat cnvt $235
driver side window weather stripping $10
oil change $20
Total damage is $770
plus labor $200

$970 out the door

 

ugh.......just got the car but, it's running good, but now its throwing a misfiring code. =/

so I will have to bring it back in the shop on saturday. hopefully wont have to pay anymore........ can a spark plug change cure this?
