I hope he gets back to me. I have a shake at 40mph at 1400 rpm. I think its an injector miss. I thought maybe converter but called brian at bts he thinks injector. Thats what i originally thought. Not sure if it matters, but i put it in nuetral reved it to 1400 rpm maybe 1200 and put my forehead on the steering wheel and could feel a shake. Went away at say 2k?? SOmetimes when driving the truck feels like the rims are oval. I need what ever tests that can be done to verify what injector or injectors are going.
Let us know what you find,my truck has the 40 mph shake as well,but only happens when at light engine load-I know my center driveshaft bearing cushion is sloppy-just haven't replaced yet to see if that's what my problem is-buzz/contribution test came out ok on mine.
