I did change all the drivetrain fluids last year as well, on top the rad was flushed. Added some supercooler additive and that helped lower Temps by about 15 degrees. It's a 2004 denali with 348,000 km's and running fine. I also just put the regular size all terrain tires on. Thanks guys.

@iamdub what rear coil spacer did you use?

Belltech calls it a "Spring distance kit". BT part number 35323.

And does anybody know if the Z71 rear coil does same thing as a 1” spacer?[/USER]

I thought the Z71 was 1.5" higher than the regular ones? Regardless, stock spring plus spacer or longer spring and no spacer will all provide lift. The different springs may alter the ride quality a little, but probably nothing significant or negative.

Well got my ****** gas mileage problem figured out for me

View attachment 230451
no you have a second code P0430 is just a secondary code it means you have another code as well

IF your cats were bad you would have Stoner code P0420 or P0421 AND P0430 (it means the first code is True)


NOT NOT I REPEAT NOT P0430 (it means anything could be wrong with it )


with
47 Enable Conditions for a P0430

and your going to believe that your cats are dead ahaha don't come crying after you had gotten scammed...

this person might work for a smog shop but is clearly scamming you




when I got the P0069 Code It had the P0430 included


after replacement of the map sensor
and rest and 2,000 miles later no more codes...


also my mpg has restored to the normal 25mpg HYW and 22 city(my city lol)

???

P0430 is a secondary code? Please explain as this is new information to me.

Edit: Never mind, you completely cleared everything up with the additional verbiage that you added 10 minutes after I asked the question.

P0430
is not a cat code


only
P0420 bank1/p0421(bank2) = failure

wasting money when you have not fixed the actual cause of the failure such as leaking fuel injector vacuum leak etc.. under normal conditions the catalytic converter will last 150,000 to 300,000 miles

Ahem....
What Is the Cause of Code P0430?
  • Faulty oxygen sensor
  • Faulty air-fuel sensor
  • Worn or internally failing catalytic converter (Most Common)
  • A leak in the exhaust system
  • Misfire (the root cause of converter failure)
  • Rich or Lean air-fuel ratio (the root cause of converter failure)
  • Leaded Gasoline (the root cause of converter failure)
