Single 750CCA 'deep cycle marine' batt on the house side at the moment. Van batt is a 650CCA unit.

Try just changing the plug wires first. They are only about a foot long each. On my Sun Voyager I can turn the wheels all the way right and change the right side from the wheel well. Left is the same. Some folks specify the wires. I used a set from NAPA. I think I could do the plugs from the wheel well too.

I would concentrate just on #4 first. Wire, plug, coil on #4. One at a time. Get rid of the code.

Default Hi Failurre Items

I have read a lot about the Chevy 8.1 V8. The ignition failures are most commonly the wires. Next in line are the plugs. I don't much mention of changing coils and I would never buy a 10 pack for an 8 cylinder motor.



So.


Pull the #4 plug and look at it. It may or may not show problem. You could swap the #3 and #4 plugs and wires and see if the problem follows. Easiest would be to swap the plug wires between the cylinders.


THESE ARE NOT AT ALL LIKE THE FORD V10 COILS


Given the age and low mileage I suspect a set of wires will do it.

Mine has a rocker switch with a musical note on it. If you turn it on the radio works. Look for one of those.

[QUOTE=Kurlon;25800]All lights working save for the compartment lights, haven't figured out how those bulbs come out. I suspect they're wedge base but don't want to get too aggressive taking them apart yet. The prior owner had ALL the manuals in a nice binder so I was able to figure out the porch step modes of operation, along with the associated lights and it's all good.

Haven't chased the mirror switch but will break out my laser thermometer tonight to see if they are indeed heated mirrors. Fuse 32 sorted my accessory socket. Rig has an appointment for a full service on the motor / transmission, so those issues will be going away soon. That leaves me the following items to chase right now:

I have a Master Compartment Light switch right inside the door where the step switch is.



Inside the door. All switches down = Normal operation. I have 4 switches.

Porch Light, Entrance light, Compartment lights, Auto steps.

He was lucky enough to get the code. A lot of the time you just have a random miss with no code. So I would delicately just work on 4 and see if the code goes away. Not messing with any other cylinder. No swapping around. That's the best way to get this taken care of without chasing your tail because you started swapping more things out than you had to.

Why the Ford coil comment? You think I only work on Fords? I was actually using what I learned on a Cadillac to give advice here.

Does it use any oil between changes?

The Ford Coil comment came from the OP seeing 10 packs for $***.

But I'll tell you I am really getting tired of beating heads with you on everything I respond to. So count me out.I will let you go ahead and confuse the folks.

Beating heads? lol

This is how you get it done when there's more than on person giving advice.


How is telling someone to work carefully using the code confusing?
