It seems the vucuum system went wacky all of a sudden on the way home. My stereo was shorting out, and I found out that it was the ground line being pressed under the clutch pedal. So I move the wire, and depress the clutch a couple of times to see if it is still hitting the wire (with the engine off). Turn it on, and find the clutch was real stiff, turned the engine off, keeps running. No vacuum to the clutch booster, or VSV. Had this happen to me at CMCC last year, but it cleared up before I could figure out the source of the problem. The vacuum system on the 13BT is a complete mystery to me. The Max Ellery manual (POS), doesn't say much about the vac system, and I only have the Toyota chassis manual. Where do I start? How do I test the vacuum components?
