"That bloody Red Baron was in a fix
He tried everything, but he'd run out of tricks
Snoopy fired once, and he fired twice
And that bloody Red Baron went spinning out of sight!"

Classic!

 

well actually this is bad info, your truck only tests actively at 3/4 and 1/4 per tank. so unless you were at said angle at the moment it self tested...nada. anything before or after those two points is irrellevant. if you have a device such a code scanner or scan guage etc that allows you to clear codes you can see this clearly

 

Zero correlation bud. The height/angle of the truck will NOT cause a CEL. Period. Not even for emissions system.

 

I like this thread

 

Pretty sure it started that way. You named the thread what you did, yet you are on board with the fact that the 2 systems are not related at all. It was pretty much an invitation for dickery.

The fact is it's just a fluke that you got differing results. You seem to be happy with the results of your suspension, now tackle the Trouble Code. Do some diagnostic work with Torque or some other tool that shows you O2 voltage readouts, fuel trims, etc to narrow down the cause. Use http://densoautoparts.com/find-my-part to get the right part numbers and have a nice day.

 

So you are going with the angle of the dangle has something to do with the code? Only thing I've ever seen throw a light is gas gauge on older cars going up or down a hill when you were low. No cel will change with angle

 

THIS IS GREAT RESEARCH! My favorite is this one:

 

Try driving with your battery disconnected and see if that solves it.
...oh and make sure you're going uphill

 

I only get the code on Tuesday’s

 

ahhh, that narrows it down
In that case you need to take all our spark plugs out, make sure they are in the correct order by length, and reinstall them

 

Did the exhaust note change? Is it possible that you have an exhaust leak at a flange or other junction whose size was changed with the change in the suspension?

 

You guys are all missing the obvious - a 1/4" lean spacer will fix this.

 

I’m still worried about the dust cap thing. I’m missing one too!!

 

When I wipe, sometimes I do it back to front. Do y’all think that’s why my hair is slowly turning red?

 

probably one of those UTI "master mechanics" that graduated every month with no experience........

or a Boatswain's mate......

 

73k miles on the truck when purchased from Treasure Coast Toyota. The code came on during the trip back home to Tampa. 94.5k miles on her now.

Removing negative battery terminal removes the code but it comes back on again fairly quick.

Here are the results from Torque (if anyone can makes heads or tails of this I owe ya one):

Make graph displays in torque to show you the bank 1 and 2 oxygen sensors. The graph is normally stable but the bad sensor will be reading all over the place. I had this code and it turned out to be a bad donut gasket. I noticed a black spot at the flange on the passenger side.

Was the truck warmed up when you took that info?
