sticky throttle

[breandan.mcilwain at gmail.com (Breandan Mcilwain)]

ok guys i went out that took the intake boot off and commenced with the
cleaning, it was pretty bad in there, also i disconnected the throttle cable
and checked it for binds and then shot some pb blaster in there to lube up
the cable.

after all the cleaning i used some white lithium grease on the throttle body
linkage and springs externally.

put it all back together and the problem still persists, i think this is
definitely a motor mount problem!

so come Thursday i am going to replace all four of those,   and also 2 rear
calipers,  rear wheel bearings, all 4 rotors, an oil change, then it will be
off to the inspection station with her!

wish her luck!
lets hope the motor mounts cure this problem
