Catalyst Problem

[Cloningen]

Hi,

I`m from Norway so sorry for my bad English.

last night i got the service engine light and when i checked the engine bay i discovered that one ot the catalyst was red of heat.

Does that meen that the catalyst is blocked or could it be another problem?

Thanks for Your replay!

What was the fault code?

But yeah, sounds like CAT is blocked.

The fault code was telling me that the engine was missfireing on cylinder 1 and 2.

Then i assume that unburned gasoline is fireing in the catalyst making in overheat.

I replaced the sparks with New one but that didnt help.

Is there a way i can check if the ignition is ok?

Where is the ignition Box located?

Mis firing is a symptom of blocked CATS.

Misfire on yours is on the same bank so could be the Pre CAT on the manifold on bank 1

Also could be coil packs on cylinder 1 and 2. Move the coil packs to see it the misfire follows the coil

Thanks alot for Your answere .

I dont have a repair book, so could you tell me where the coil pack is located?

[ChrisIS200SportTTE]

Each cylinder has a coil pack. It's right on top can't miss it.

A coil pack takes the 12 volts that your vehicle system uses and it multiplys that voltage to anywhere from 15000 - 45000 volts and sends that to the spark plugs to ignite the air / fuel mixture inside your engine.

No offence but if you don't know what a coil pack is and does and where they are located I think you may need some professional help
