Both banks below threshold. I can get the cats for both sides all for alittle over $600 but the truck has 230,000 on it and money is tight right now. Will it pass emmisions if I reset the computer before they plug into the obdII port ?
What will happen if I just ignore it ? Thanks

 

What will happen if you clear the code and go to have it tested the emissions scan will read monitors not ready and they will tell you to go drive it 50 to 100 miles and come back. In that time the codes will return and you will fail the test. The only way to get rid of the codes is to make the proper repair.

 

Hey Lou, try gutting your cats or getting two high flows put in place of the four factory cats. Should cost less than $250 for two high flow cats. And if you run the truck for just a few miles, you won't have that systems not ready light. Done it several times to beat the "emissions" tests we have here...

 

I think I remember seeing some cheap cats in the JC Whitney catalog. Might be an idea

 

well I reset the computer and cleared the codes before I left for work, Drove over 120 miles today and no CEL yet.

 

Too early. Need two consequetive drive cycles in which the cat efficiency monitor runs and fails to set the CEL.

Install MIL-eliminators (about 3 bucks from Radio Shack for parts if you can solder) and GCAP will never know the difference .

Additionally, you can get a pass with one monitor incomplete. If you know what you're doing, you can get it through e-test that way.

was looking for a new cat for my 02 SCrew and this may helpout...not too expensive...the magnaflow at the bottom is for a 5.4...and only runs about $75.00. Anyone know if that will fit on the 4.6? I dont see a problem as long as the in/out pipes are the same size...

Due to his Truck being a 1998 He cant do the 2 for 1 Swap. That will only work if his Truck was a 96 and older.

 

Let's hear why not...

 

Due to Federal Guide Lines this cant be done on a OBDII vehicle legally.
