Any of your calipers stuck?

Nope. They were fine. Just the lack of grease was causing the sticking and the old rotors were causing vibes.

 

[uss2defiant]

Great!
I got to look into my driver side front brakes.
Started to make that screeching noise at the starting part of the braking.

 

[CzarKJ]

P0171. Cleared it and it came back. Looks like I have some cleaning to do.

 

[CzarKJ]

Cleaned the MAF sensor and throttle body. Engine light went off on its own. Bonus:Removed a mouse nest from under my resonator box... since my Jeep gets driven every day I'm curious when they put that there haha

 

[uss2defiant]

wow. all the way there???? hope they didn't chew into any wiring.

I guess the mice in Massachusetts don't fool around when it comes to construction projects. They could teach the highway road maintenance department in Cleveland a thing or two.

 

[dude1116]

Maybe they climbed one of those tall snow piles you have

 

[CzarKJ]

Nevermind. It came back. Hmmmm

That code (P0171) indicates a lean condition on the left/driver's side bank. Check all your vacuum hoses, especially the ones back against the firewall. The largest one at the very back of the cylinder head typically splits right at the fitting on the cylinder head and creates a vacuum loss.

That code - and it's brother P0174 for the right bank - are a pain to track down and fix. It's possible it's an O2 sensor going bad but most likely a vacuum leak.

Thanks for the info! I know I have a vacuum leak due to when I'm going uphill in a high gear my defrost kicks on. Time to really get looking and possibly smoking! I know what I am doing tomorrow....

 

[profdlp]

Good luck, Czar.

 

[CzarKJ]

Well then....

You must be registered for see images attach

Going to clear the code and see what happens.

 

[uss2defiant]

where did you find that cracked hose?

 

[profdlp]

where did you find that cracked hose?

In the Land of the Giants, apparently. :gr_grin:

 

[CzarKJ]

Crankcase breather tube. Not my issue though. Went to clear the code and p0131 came up. Bank 1 sensor 1. Ran to napa and picked up the sensor, ntk of course. Now I'm taking my skids off and letting the exhaust cool down

 

[uss2defiant]

ah. just replaced one of mine.

 

[CzarKJ]

ah. just replaced one of mine.

I'm looking at this one right now.... how the hell do I get to it without taking out the engine...

 

[uss2defiant]

are you referring to the one close to the firewall by the valve cover?
which side are you working on?

 

[CzarKJ]

Bank 1 sensor 1. Above the driveshaft. Under the steering column.
