I had a stumble on semi hard acceleration in first gear only. Checked all as reqiured. Vacuum pump is cylcling on and off. Seems to be the secondary solenoid. I unplugged it and replaced it with my original that I keep. Original was working two years ago, but I replaced it as a maintenance issue. New didn't last too long.
Does the soleoid fail by leaking vacuum?
Could that create a stumble under semi hard accelerartion?
