Hey guys I had just bought a 2001 jeep Cherokee sport pretty new to them still and recently when I'm driving and then stop my oil gauge goes down but then when I start driving its back up to where it normally is any ideas to what might be doing this?

(I think it might be the sensor not sure though)

 

Scored a factory tire carrier but nothing else was in the jeep. Just wondering if anybody could give me a parts list and pics for the carrier

 

That's normal

 

So nothing to be worried about then?

and do u think it might be the sensor though just want to be sure

 

the oil gauge tells you the oil pressure. oil is fed through the engine by a pump that spins as the engine does, at idle it is pumping slowly(low oil pressure), at high rpms it pumps faster(high oil pressure), the faster the engine is spinning the harder the pump is pumping, ensuring that oil is moving through the engine as needed to lubricate all the components.

 

I've got a quick question. I have a 93 5 speed and have been getting around 18-19 mpg average. things just started to cool off for winter here in oregon and i suddenly just got 12 mpg that drop seems too big to be cold weather and witner gas could it be a bad 02 sensor?

 

I've searched the forum and not really found what I'm looking for, maybe somebody can point me to a related thread.

my new to me 98 jeep xj sport, 4.0L, AW4, stock height, 225/75R15(fairly new), 163k Mi on original engine trans etc.

I found the truck makes a cycling droning noise between 60mph and 70mph(100 - 120km/hr), it's not overly loud but noticeable, there is a slight vibration throughout the truck that is more continuous than the cycling droning noise. I'd say tire balance for anything around this speed but the tire balance does not "cycle".
the cycle is very consistent, kind of a wraaoooow wraaoooow that is one second on, one second off, repeat. haven't pushed it too much past 120km/hr but it's cycle does increase relative to speed, I notice nothing under 100km/hr

any thoughts?
my vote goes mostly to the rear gear set, since it is the only thing that I can think of that has a cycling variable(small gear to big gear) but transfer case and slush box also qualify under that definition. my feeling thus far is that the issue is coming from the rear, but I've had other vehicles trick me with a sound/feeling that travels through the vehicle leading you astray

 

I gota loud popping sound when i turn left and go over a bump coming from the front driver wheel well, problem?

 

Thank you 1976 Mustang... I'll do that!

 

OK, I just checked with my buddy, I have it wrong, I should SUBTRACT, because if my GPS is 50 and speedo 52, because the speedo/odometer are showing more than the actual miles.
So, the following is the correct example:
To calculate the true MPG

1. Fill up at a gas station, record mileage or reset odometer.
2. Run near empty, fill up. Record mileage again or record odometer.
3. Subtract mileage from #1 from #2, write down if needed, or just use the odometer readings.
4. Now at this point, take that reading, and subtract or add your '4 %' or .04 or whatever offset you are using (plus or minus)

Example:

Total odometer reading for trip = 320 miles times .04 = 320 x .04 = 12.8 and then subtract that from 320 = 307.2 total corrected trip miles

5. Take 307.2 and divide by the number gallons on fill up: 19.2 Gallons

307.2 / 19.2 = 16.0 mpg

And there you go. TRUE 'average' MPG.

Why won't it run hotter!!!!!???


It's hard to tell but when I'm driving 20mph or faster its barely on the first line

 

Did you replace thermostat lately.

 

No sir, about 8 months ago I put in a 180 t stat. I was going to put in a factory one and see what happens.

 

Did you get the factory bumper with it?

 

Well then thats completely normal. Look at where the hand is, its not too far from the 180 mark. Take into account the inaccurateness (yes i know, not a word) of the stock readout, that puts the temp at probably right at 180.
