I want the skinny on these two things

[mackconsult]

I put my van in N when coming to stop at lights. Just seems like the van runs smoother when not in D at lights. Is there a problem with this?

My van goes into limp mode still when on WVO, trying to figure out why. Noticed that you can shut the ignition off while moving, then back on and the engine comes on again with the limp mode clear. Is there something wrong with doing this?

Inquiring minds want to now???? :idunno:

If you shut the ignition off while underway and the steering locks out you could be in serious trouble.
In California it is against the law to turn it off underway.

[mackconsult]

This is true if you turn the key all the way, but I only turn it to ACC and then back to ignition.

I am just asking to find out about possibly damage, not legality.

Putting in neutral isn't the same as shutting it off. You can put it in neutral. It uses less fuel. It pisses off the people behind you who have to wait for you to shift into D. Possible sharp shock to tranny if you step on the gas and then shift.

It's almost second nature now. I coast to stop and pop it in neutral, then back in gear just as the light changes. It's all smooth in the van, and no one has got mad at me yet at a light change.

The manual says to only put in N for longer term stopping. Don't coast in N, that will screw the tranny.
My thought is the slight clug in and out of N would put additional wear on the tranny.
I would think that the WVO might be too thick. Changes the pressure in the lines or some such.
If your rig is smoother in N than stopped with D, you might have an issue. Possible clogged injector. Black death. Filters. Mine has no difference D/N. only the pushing aspects and idle, no additional vibrations.

Do you heat the WVO to reduce the viscosity?

[mackconsult]

No, its none of that. The vibration I refer to from D to N is vibration in the truck itself. I am pretty sure its normal because its always been there even on the diesel side.

Shifting from N to D and back there is no clunking what so ever. Its very smooth. I think the manual says don't go from D to N for like maybe high way speeds and such. I put the truck in N from D just before it gets to a stop.

[mackconsult]

Yes, its a V3 frybrid kit.

I notice the same thing and my Sprinter has a new engine with only 15k on it. :smirk:

I notice the idle is just rough enough to make the pens and coins rattle in the doors sometimes but only when the van is cold and I attribute this to the viscosity of both the diesel fuel and the engine and transmission oils.

After the van has been fully warmed up it idles really smooth.

Personally I wish the idle was a titch higher.

A while back in another thread an idle adjustment at the throttle pedal was mentioned, but this was for an early T1N. Has anyone (successfully) tinkered with their pedal assembly to raise the idle speed or is this playing with disaster? My T1N idles naturally & noisily at 660 RPM but like a dream at 750. If I could adjust the idle to 750 I would. Thanks.

Yep, It is the sign of a strong motor having experienced many hours of it on commercial fishing boats.

There may be a way to do it on the DAD.
