Strange event on way home
Pulling from a stoplight I took it to about 4k RPM, light throttle, then shifted to 2nd. All of a sudden my car started surging, the Rpms bounced from 2-3k and the traction control started flashing. It felt like I was on a motorcycle with a flat rear tire with a loppy bounce and a weird side to side wobble. I turned off the traction control real quick and pulled over into a parking lot.
When I pulled Into the lot I left it running. It idled fine and sounded normal, no flat tires, nothing was in the road for me to break loose on. When I got back in and started driving, my car was abnormally quiet. I have the Roush AB and normally it's pretty rumbly from idle to 2500ish then it gets loud and kind of buzzy under normal throttle. Well now it doesn't sound the same, it's the same rumbly sound all the way up to 4k-ish(I didn't go higher).
To me it sounds like the vvt is not changing over. It was abnormally quiet the whole ride home, about 55miles. It drove smooth, just abnormally quiet from what I've experienced with the Roush. I didn't notice any of the distinct valve shift tone change, it's almost like it's not doing the vvt thing.
I did notice on my way too work this morning, in 5th about 2500 I had a weird high pitched drone like buzz and in 6th under 2k the hum was almost unbearable. Almost like someone had a 15" sub with 5000 watts aimed at my face. This has been sort of normal for the last 3k miles I've had the Roush on, just normally it's less annoying/noticeable and not as loud.
So my conundrum is, was it normal before and now it's broken, or was it not normal before and whatever happened tonight made it normal? The way it sounds tonight is not bad it's more subtle, a distinct growl, no buzz at all until 6th gear at 1500-1750rpm and even then it's 80% quieter than it normally is.
The Roush AB is my only mod atm. I have 5500 miles on the car. It's a 2014 base 6mt.
