I agree it it weird, I'm curious to think maybe if there was an intermittent short or something of the like against the manifold that caused a wonky fuel ratio thus the cat code...things that make you go hmmmm.
Reporting back. I found the bank 2 sensor 1 o2 sensor connector simply laying on the manifold flange where I'd connects to the head pipe melting away. Thankfully it was the sensor side of the plug and the truck side seems ok. Naturally I replaced it and my troubles so far have seem to gone away...
Interesting the cap can fail in such a way. I see what you're getting at those pathways pass extremely close to one another in spots. A crossfire would be easy to happen under these caps. Good tips thank you, I'll definitely report back
Thank you for the schematic sorry no the code reader is not live data capable. It is indeed the cat code bank 2 p0430. I certainly can chase back the circuit and report back
I may have transposed a digit. The code description is catalyst below efficacy threshold. They way its behaving leads me to think it's a symptom rather than a bad cat. Given the back fires and hard starts my thought was possibly rich condition or egr malfunction the o2 sensors (all4) are a year...
Hi. Thanks for your response I may have transposed a number but the description is catalyst below efficiency threshold bank 2.
It's the only code and has been the whole time. First intermittent and now steady.
What I'm hoping to achieve is the answer to this question...is the cat bad or is it a...
Hey all, 98 c1500 5.7 ex cab short box 2wd
This is one of those "the other day it started" stories with a p0403, the mil lamp would come on, go out, come on, go out now it's on steady. During the time of light coming on and turning off (which lasted about a week) at times the truck would start...
Here is this weekends finished result. I know I got paint on my shocks was kind of hurrying towards the end...I beat the snow!
Sway bar came from 03 avalanche and the links. Axle mounts were cut off 98 tahoe, the rest was custom built. Took me a few days but it's done and it's on rails compared...
