More of just a shake..
But Driving my '89 around today.. i notice on slight inclines in 3rd, around 1300-1600ish RPM and typically around 5 inches of Vacuum, the Engine starts to shake, even up through the steering colum.. but if i ease off or onto the gas.. (enough to move the Vac/boost guage from @5inchs of Vac) it goes away..
Haven't tried it in 4th.. and 1st and 2nd is hard to get it to stay there (less load thanks to the TC not being locked up)
Other wise the car idles and runs smooth.. and gets decent boost (for a 120,000mile engine) There is the odd starting issue (a fair amount of cranking then it finally fires, along with a mild rough idle when it does it, 'till it clears itself or you blip the throttle, whichever comes first) , along with now the IRCM keeping the cooling fan on..
I amit this is minor, but annoying thou, since around here, people are to scared to push the gas pedal to go up a Hill, and being that the AOD's TC is locked in 3rd and 4th, it can be loaded down nicely
