A strange thing happened last night.
I was on the freeway interchange and about to enter a bend, when I noticed that the brake pedal was harder than normal and had little effect. When I let go of the brake I immediately noticed that the car was moving with no input, almost as if the cruise-control were on.
While finding a place to pull over and trying to slow down, I noticed that the revs would jump sky high (> 5000rpm) if I disengaged the clutch. Ended up killing the engine and rolling to a stop at the side of the road.
Unfortunately I have not been able to find a root cause. I am willing to accept theories such as the throttle being stuck open, although the throttle linkage seemed to be in the right spot, and the cable did not appear to be caught anywhere when I checked it.
Was able to start it up drive home normally right after.
I think my biggest concern right now was the momentary lack of brake assist, which had never happened before. I am trying to understand whether it was because of a possible stuck-open throttle or because of a vacuum leak.
The wiring harness to the cruise control was disconnected. Is it recommended to remove its connection to the throttle as well? I can't seem to get a good view of how it's attached.
Thoughts? Car is a '95 CSE 5-Speed (no TCS).
Thanks, in advance.
