'94 850 stickey accelerator peddle

I have a '94 850 wagon. The accelerator peddle sticks frequently.
When I try to use it I usually have to push on it fairly hard which can
cause a jack rabbit start or acceleration.

Where are he lube points I need to check.
This is not the turbo version.

Thanks

This is a well known problem. Routine dealer maintenance should prevent
the problem. The solution is to clean the throttle body. A buildup of
deposits causes excessive friction with the throttle lever. Our dealer
has further found that adjusting the throttle so that it doesn't quite
go completely off will help prevent the problem.

It is a very dangerous problem if one uses cruise-control. What happens
is that when you go down a hill with cruise-control on, the throttle
will go to the off position. Then at the bottom of the hill the
cruise-control will not be able to resume control until the car has
slowed down enough to cause a large force on the throttle which causes
very high unexpected acceleration back up to the set-point when the
force overcomes the sticking. It is scary.

I have a posting on this on my Volvo website.

 

Thanks Steve...

That is VERY helpful.

I had to change the throttle cable on my '98 S70 (same as 850) to
restore total throttle smoothness.
