Need your mechanic thoughts

[johnr]

That boat would like much nicer behind a shinny new eco boost Ford F150.

spend it up dude.

Does it get better when the engine warms up? Acts up when cold start?

Also, look for broken exhaust manifold to head bolts, these tend to break off and can suck air into the exhaust causing a lean condition as the 02 reads air fuel ratio after the exhaust manifold. You could also ohm resistance in the 02 sensor (check both fronts) as this will give you an idea if they are bad. Check fuel pressure as poor pressure will usually indicate lean on bank 1.

Thanks callem, I'll pass along the info to my friend.

 

[SDMF]

if its a plug issue wouldnt you expect it to run shitty all the time, and not just idling?

No.

 

[Sub_Elect]

Sooooooo, I am boatless for the entire spring and summer Dirty. I would think my pickup could pull your new tiller from ramp to ramp until you get your pickup figured out.

Guy had another offer on the table and I didn't know for sure if my boat was gone yet. So, I don't know if I got it.

Were you able to get this issue resolved? The codes that you pulled will likely have nothing to do with the O2 sensor or the plugs. The PCM sends P0171 when there is a vacuum leak. Unfortunately, there is not quick and easy solution for this. The P0300 could very well be an injector issue.

If you're still going to try the O2 to rule it out, do yourself a favor and just buy a few O2 simulators. They are MUCH cheaper than new sensors and they will get you by just fine. If the plugs and simulators don't work, you may have to take it in, as diagnosing vacuum leaks can be a daunting task.

The new boat will do you no good without a way to pull it.

Did you tell him that you had 93,244 NDA points ??

Does he realize who you are ??

Seriously though, hope you get it.

Even offered him one snooty patooty. He obviously doesn't know the value of it.

I'll know more after today. I trust my friend as he does plenty of side work and has always fixed whatever I brought him.

I'll kick in a patootie and a red tiger x-rap too. THAT'S saying' something. Norm, i hope he gets this boat too. Seeing as how I can drive by ever policeman in the state, legally, after an entire day of fishing, I can be your guys' Bwanaa.

You know, the Jimmy was available for like a whole month there. You could have scooped it up.

haha. another item that has fallen through my fingers.

 

[Callem'In]

So...What fixed it? I was suspecting leaking intake gaskets, but needed more info to be sure....

 

[DirtyMike]

You might be right as the plugs and wires didn't do it and even though bank one sensor one was bad and replaced, it still has a CEL and small misfire.

 

[Callem'In]

Spray around the intake with brake clean or carb spray when the engine is cold. If the rpm change, the intake gaskets leak causing your lean condition and misfire. The GM LS engines are notorious or this problem. if you test fuel pressure, 55-60 psi is where it should be at idling. Anything less and you can also get a bank 1 lean condition.

 

[DirtyMike]

I definitely appreciate the help. Hopefully I get this thing narrowed down soon. I don't like check engine lights.

 

[Captain Ahab]

Put a piece of electrical tape over the Check Engine light and turn up the radio?

 

[guywhofishes]

210,000 miles on my 99 Ram. Never had a check engine light.

Just sayin. :;:howdy

my old blazer in highschool i traded in with electrical tape over the CEL. I always have wondered if they noticed when the dealer dude test drove it.
