No, the mount was one of the things the dealership changed in their $1500 fix that didn't fix the problem.
What was done prior to this happening was my mechanic had just did the 100K go over. He said he changed the plugs, wires, serp belt and tranny fluid. My UIM was leaking coolant or something so the receipt said he got a "plenum gasket kit". It ran beautiful for about 3 or 4 days when I got it back from him then this started happening. The temp was about -10° that day. Today is warm (47°) so I wonder if the working good has to do with the weather???
Since it'* running comparatively good today and the only time I could get it to chug was wen I kicked it into passing gear. Unfortunately it didn't fail that every time I got it to chug someone moving slow got in front of me and I had to back off.
I couldn't figure out how to get the current gear PID to register but what I'm doing and letting the car coast until it settles into a gear then I go WOT which kicks it into passing gear and is the only time its messing up today. It doesn't do it 100% of the time. More like 30% today.
