Ok so here is an update on this. I finally took the car to the dealer as my warranty is about up(73,000 total miles now). They said the engine mounts are still in good shape. They said they could feel a very slight vibration but it was normal to them and not what they see when the engine mount fails. The vibration is differently coming from the VCM kicking on and off and is most noticeable when it kicks on in ECO mode. It is a very slight vibrations and I thought the dealer tech might not notice it but it is definitely there. I'm just going to keep my VCM Muzzler installed. Here is a post I made about it in another thread:
If so, what are your findings using it? I installed one not quite a year ago because VCM mode was starting to cause odd vibrations in the car. I think it works pretty well at keeping the eco mode(VCM) from coming on 90% of the time. Some times in stop and go city traffic when the engine temp gets higher the VCM Muzzler fails to keep the VCM from turning on until I start cruising again and the engine cools off a little. I installed a stronger resistor(forget the OMH rating) and it was to much and kept the temp down to low and made the check engine light come on. Even the stronger resistor failed to keep the VCM off in city driving so I installed the original resistor and that keeps the CEL off while still preventing VCM from activating.
My car is much smoother overall and does not have the odd vibrations when the VCM operates normally without the VCM Muzzler. Also at nearly 75,000 total miles it burns zero oil between 5,000 miles oil change intervals. I'm also getting the exact same gas mileage with the VCM vs. when it was not installed which is 24-26 city and 27-30 highway. What are your finding on this product and what do you think of it? Are you getting 100% VCM deactivation with the Muzzler or does the VCM still kick on and off when it gets hot? What color resistor are you using? Thanks everyone!
