Re: Low gas milage, rough start.
Jade, the gauges not coming on with the key is a common problem caused by a poor connection in the back of the gauge cluster. Short term fix is to pretend you are a pissed off guy and smack the dash with your hand, not fist. That usually does it. Not sure if I told you to do this, but if the O2 sensor hasn't been changed, like when that last tune up was supposed to have happened, putting one in is a good thing and may help smooth it out
Re: Low gas milage, rough start.
Cant say Id be opposed to giving it a good smack at this point. Shouldnt even have to pretend on the pissed off part. Not sure if they put a new O2 sensor in with the tune up but I didn't see it on the receipt so most likely not. It just passed an inspection so I just wrote that off (probably not my best idea). This is probably a stupid question but is there any way to test the sensor to see if it's still good or do you just have to bite the bullet and hope a new one fixes it?

Re: Low gas milage, rough start.
Not a stupid question. Yes you can, but it takes equipment I don't have. My rule of thumb is change it every 50K. And while you are at it, the crank position sensor and cam position sensor every 100K. Those two will leave you stranded when they quit. Basically what happens is that the O2 sensor generates its own electrical current. Eventually it starts running out of electrons it can get rid of so it starts generating less current and causes the engine computer to assume the mixture is lean and so it squirts more fuel into the cylinders. Short story is that they wear out just like solar panels
Re: Low gas milage, rough start.
That would make sense. I think I'm back at 20 mpg highway again but my exhaust does smell pretty rich. And I'd bet money that none of those 3 have been replaced in eons. The jeep is a reformed mommy mobile and I'm learning pretty quickly that she ran it hard, put it up wet, and decided maintenance was for suckers.

Re: Low gas milage, rough start.
That could be. Mommies like to feel acceleration too. 20 mpg is good though. Those of us with lifted Jeeps get less
Re: Low gas milage, rough start.
And letting Reese's cups hang under the back seat until petrified apparently. But yeah, thought it would be a bit of a waste to lift a 2wd. Just trying to get it running decent before I sell it next summer. And keeping it running to get me to classes and work in the meantime.

Re: Low gas milage, rough start.
It will be a good rig for that. You might even decide to keep it. You could call a paleontologist in to see if there is any evolutionary value to old vs new cups :D
Re: Low gas milage, rough start.
Ah, darn. Already partially removed the thing. Coulda been rich!

Not to mention a whole new field of GMO vs non GMO peanuts :D
Re: Low gas milage, rough start.
There's something genetically modified about that thing, that's for sure 😂

I am sure. Or perhaps you can smuggle them into Egypt and sell them to a tourist saying they were just excavated from a pyramid :D

Or that guy from ancient aliens. I only have one so gotta make it count 😁

That is right, chance favors the prepared mind. If it is alien, maybe it is paranormal
Re: Low gas milage, rough start.
Bender the jeep and it's haunted petrified Reese's cup. That's a whole episode right there

You could start your own blog with that right there
