Don't waste you time cleaning your 02's, replace at least the 2 fronts.
As for the misfires, all on the same bank, it is not coils, I have seen this come up before, plugs, wires,02's and coils won't fix it and I cant remember what the cause was in the past, but I see that combination 3 or 4 times a year.

 

The CKP (crankshaft position sensor) tells the ECU where the flywheel is so spark timing can be spot on. If the sensor fails, no sparks. But if the tip of the sensor bent or coated with metal fuzz, perhaps that is a consideration. The ECU also uses input from each knock sensor to adjust timing, but knock sensors should be tight against the block on each side. Also don't need any corrosion in the connectors between the coils and the ECU. The ECU turns the ground on/off to fire the coils, don't need a stray ground. Small three wire plug on each coil. Don't need to be swapped either.

 

i bought the o2 sensor and coils. I will install and let yall know.

 

Save your time, it is not the coil, believe me when I say this.

 

Ok. I am going to check the crankshaft position sensor and replace the o2 sensors. could a leaking exhaust be causing the knock sensors to register?

 

Mike, after reading your post on the CPS I did a search on the forum, and I think you hit it with that. I will have one in the morning and will replace it tomorrow after work and let you guys know. Looks like I will have a couple of extra coil packs around the house, at least I hope so, wasn't looking forward to replacing those!

 

The CKP goes block, sensor, spacers, nuts.

 

I had similar codes back in Feb.(12 to be specific) and it turned out that i had a leaking intake gasket that i couldn t see leaking down the back of the motor. Also my valve covers were leaking oil and dripping on the csp cover and o2 connectors. When all was said and done i was still getting the 0130 code for b1 s1 circuit, after much cursing and frustration i finally had to have the computer flashed at the local rover dealer. I would clean any excess oil away for the connections and clean the connectors really good first and see if you still get all the same codes. Hope this helps, i know how frustrating o2 problems can be.

 

Thanks Savannah, I was wondering about that!

Love-Hate, I will definitely clean all that up as well, this thing leaks some oil. do they even have gaskets on these vehicles, lol?

 

Well I was wondering the same thing when i saw how much oil was coming out of mine.Lol. Actually you might SLIGHTLY tightening the bolts to the valve covers,(its a 8mm 12 point socket) it could slow it down till you swap the seals. I say slightly because it doesnt take much to snap them then your in for a lot longer of a job. My leaks ruined a crankshaft sensor and left me sitting in the middle of an intersection. Damn these trucks are heavy when your the only one pushing!! and its Jack, now that my 00D2 is running near perfect i need to change my user name.
