Its looking like today is gonna be another repair party at my place. Bring your junk. The beer is already on ice
I was going to pop over and hang out after doing some things earlier in the afternoon - but as I was driving down the freeway earlier, my check engine light came on, then randomly I felt loss of power....occasional backfire if I gave it gas while the power drop was happening...freaked me out because I was just getting on the Coronado bridge...so anyway, I got over the bridge, pulled over and let it sit a minute and then continued on...it was better for a bit...then started doing it again randomly... Got to where I was going and checked the engine codes using the key trick...I got a 12, 21, 42, 55....the same ones I ALWAYS get...when offroading in the desert with the dust, etc...and it always goes away eventually.... For easy reference they are:
12* Battery Disconnect Direct battery input to the PCM was disconnected within the last 50 key-on cycles
21** Left O2 Sensor Shorted to Voltage Left oxygen sensor input voltage maintained above the normal operating range
21** Upstream O2 Sensor Shorted to Ground; or Upstream O2 Sensor Heater Failure; or Upstream O2 Sensor Slow Response Upstream O2 sensor voltage too low, tested after cold start; or Upstream oxygen sensor heating element circuit malfunction; or Upstream oxygen sensor response slower than minimum required switching frequency
21** Downstream O2 Sensor Shorted to Ground; or Downstream O2 Sensor Heater Failure; or Downstream O2 Sensor Shorted to Voltage Downstream O2 sensor voltage too low, tested after cold start; or Downstream oxygen sensor heating element circuit malfunction; or Downstream oxygen sensor input voltage maintained above the normal operating range
42* Auto Shutdown Relay Ctrl Circuit; or No ASD Relay Output Voltage at PCM; or Fuel Pump Relay Control Circuit; or Fuel Level Sending Unit Volts Too High (or Too Low); or Fuel Level Unit No Change Over Miles An open or shorted condition detected in the auto shutdown relay circuit; or An open condition detected in the ASD relay output circuit; or An open or shorted condition detected in the fuel pump relay control circuit; or Shorted (or open) circuit between PCM and fuel gauge sending unit; or No movement of fuel level sender detected
55* N/A Completion of fault code display on the Check Engine Lamp (MIL)
So then I popped the hood - didn't see anything...then looked underneath. I found oil all over the place on the underside - mostly on the driver's side...it looked to be originating from a line I can't identify - I don't have much experience wrenching (I was planning to supervise, lend muscle, and eat food at Jason's and check out his new CJ). The leak looks to be a little ways back from the front tire area a little bit and on the inside of the frame. At least that is where it looked to be coming from - hard to tell with oil all over.
So I got it home and took some pictures...I called Jason and talked to Steve a little bit -to find out where Jason lives...thought it was OB for some reason, which is close - I would have driven over there still...but found out he is in east Poway...and I couldn't risk driving it that far and I don't have another car so your food is safe!
Anyway, I will probably take the Jeep into ORW on Monday, because they just did my re-gear and had things apart this past week...so odds are it may have been caused by that...but I am not sure...so I am posting the pictures I took below and maybe you guys can help me diagnose it ahead of time...I need to check my oil level before I drive it anywhere in any case...it looked like engine oil to me.
What do you guys think? Can you tell anything from the pictures?
