[Shotimes] VAPS problem & question

The unbelievably stiff throttle spring on my 94 bothered me even more
than the light steering.
I had the 89 side by side with it and compared the throttle assemblies.
Unbelievably the 94 had a set of three throttle springs that were both
thicker in diameter and wider than the 89. There were twice as stiff IIRC.
I bought a spare 89 throttle body and swapped the three springs only. 10
min job. I left the throttle body intact as weel as the white sleeve
that supports the springs. $7 mod!
Got some pics if you want me to e-mail them direct.
