I just got a '88 2.8L motor running after it had been sitting for a while. I bought the vehicle when it was not running, so not sure how long it was in that condition.
It is running, but has a high idle, and I thought it had a vacuum leak.
Now I realize the throttle is not seating completely closed, and can be closed further when turned and closed by hand.
I had to wrap up the days work by the time I realized this, so I have not spent much time on a trouble shoot.
Does this sound like the throttle body plate area just needs a good cleaning, or could there be other causes for it not to seat closed fully?
The Topic title may not be very accurate, as it really is an issue where the throttle is not completely closing by itself, but can be closed when turned by hand.
Thanks for the help.
