Hi all! First time here. I have gone through quite a few threads not finding what I need. So here it is. A month ago it started chugging when I was to stop. The VTM-4, anti skid and engine lights were on. I did the restart the manual suggested. It didn’t work. So I had it towed to Honda. Found out that it was running on 3 cylinders and the spark plugs were gummed up with oil. So the engine was ripped apart and 3 O rings were replaced.
All was well for a month. Now when driving the battery and VTM-4 are on. BTW the drive shaft is not in and is going to be replaced before snow flies.
Wondering if anyone has had this happen and if these two problems could be related?

To prevent the spark plugs from fouling out again, I’d disable the VCM. This will keep the engine running on all 6 cylinders 100% of the time. I use S-VCM that’s made in Canada.

S-VCM Controller - Disable VCM / deactivate VCM and stop ECO in Honda Acura

Deactivate Honda VCM in 3.5L V6 SOHC engines. The S-VCM Controller is an automobile grade, high precision tool that can reliably disable VCM 100% of the time, and would safely bypass in case the engine overheats. It does not use a fixed resistor or manually adjusted potentiometer, and is a much...

It would be really helpful to have the trouble codes that’s stored in the computer to be better able to assist you.

I agree with nail grease. However, if your plugs are oil fouling then you may have a piston ring issue. The ring issue is bad news and usually constitutes an engine rebuild. Check out the class action lawsuit for this problem with the 2013 vehicles.

S-VCM reversed my oil consumption and fouled spark plugs. Gasoline is a great cleaner of parts. With the cylinders firing 100% of the time, there is a good chance for the carbon deposits to burn off. Highway speed drives really help after the VCM is disabled.

The engine was already ripped apart and 3 O rings were replaced with new spark plugs. Now have the issuer with battery and VTM-4 light on. When you drive it it doesn’t feel like it is changing gears correctly. Also before this all happened we had coolant leaking.

. updade took it into Honda and it was the alternator. Drive shaft on order to rid us of the VTM-4 problem.

Welcome to the forum. Sorry to hear you’re having issues with your Pilot.

I did get it sorted out at Honda. Ended up being alternator and also had drive shaft put back in. Fingers crossed no more problems. When it rains it pours!
