Take a look at the member list dude. Only 64 people have more than 100 posts, and I doubt many of them are still active. Oh, and you have 4 whole posts so far.sandcobra164 wrote:The P0430 code is gone. Now to address the fuel sending unit. I know this an oddball question but I'm providing the last 3 replies on this post. Do you guys have perfect trucks that never break. I've seen tire's and wheels threads that get replied to alot more. I'm a member on SteelSoldiers which is an ex military big truck site and big truck owner and they at least participate on the forum and much more in person.
The fuel sender replacement was pretty straightforward and you can find links to people showing photos of how to do it.Tech wrote:just search for the P0463, you'll find TONS....including at least a couple how-to's.
The front "02" on R51's isn't an 02, it's an A/F sensor, which works on completely different voltages than the conventional 02. As long as you don't mess with the primary cat between the a/f and rear 02, you can do whatever you want to the rear cats. You don't even really need to worry about keeping B1 and B2 balanced. The injectors aren't batch, but sequential. The ECM will take care of it. If you bust out the matrix from the cat, make sure you do a COMPLETE job. The broken down material can get sucked UPSTREAM ( believe it) and turn your engine into an oil burner.
There are 4 cats, 1 between the FA and O2 sensors on each bank, and 1 after the O2 sensors on each bank. I think they just clean the exhaust more.skwerl wrote: The article states there are 4 cats on an '05 are you saying their is only one primary and two secondaries?
It has some good info on how to test the cats if you have an infrared thermometer. I may try that but I still plan on taking them off anyway to try and look at the honeycombs.
You say not to mess with the primary cat between the AF and O2 sensors. I assume you mean not to remove the honeycomb inside the cat, right? Since it has to function and give correct readings between the AF and O2 sensors. If that one is bad, I'm pretty much going to have to buy a new one. What's the chance it's just a bad AF or O2 sensor?
