I ordered an Ultra Gauge and got it in today. The new models do have the ability to monitor the voltage. it is not reading at the battery but at the port so this reading should be fairly close to the battery voltage.

Now the question that I have, well not really a question more of a observation but I am getting an alarm that is Bank 1/Sensor 1. I have pretty much ran through the LRM search and what I have found that it isn't anything to worry but I should watch the O2 sensor and compare the readings to determine if one or more of sensors are failing. I have been experiencing and occasional stutter when running. This error can last a few seconds or for several miles. It seems to occur when the tank is above 3/4 tank. I have owned the truck for about 10 months about 7ooo miles. Just throwing this out any input, even the mean kind will be helpful.

maybe just putting some new plugs would help?

 

Turn off the alarm's on that thing, it will still give you the trouble codes and what not it just wont yell at you and scare the living hell out of you while driving.
What is the code you are getting?

 

that is the odd thing,.. no codes just the alarm

 

Getting the exact same thing...Bank 1 sensor 1 Value 8895 should be 2000 something...

Turn those damn alarms off, they are not applicable to our trucks.
If you read the owners manual....

 

Owner's manual. Who needs that, I have google and this place!

 

I shut off all the alarms but left the High H2o Temp set and the road speed set at 67 mph and the voltage. Changed the spark plugs, the old ones were clean but worn...now she burrrrs. Odd tho the idle speed while in D has dropped 150 It idled at 850 rpms before and now 675, but it is smooth with no stutters. So I am going to shut up and enjoy! Now what to spend money on....

 

Turn off the O2 temp sensor setting, it does not apply to our trucks.

 

will do, thanks

 

..but if your wife drives set an alarm for 2000 RPM
