So I was going to move the TC out of the garage to work on a different car for once. I had it idling for a few minutes before I moved it and while it was idling all of the sudden the idle starts going crazy. It would bog down and shoot back up over and over again. This is similar to what was happening before I changed out my VAM, but it didn't feel the same. I could also not correct it and shutting of and restarting the car didn't help.
Well I moved it and finished what I had to do on the other car. When I went started the car up to move it back to the garage it did the same thing. I took it around my driveway and when I got close to the street and hit the brakes the darn pedal went all the way to the floor with almost no resistance whatsoever before it even started braking. Brought it back up the other side of the driveway and when I got back to the garage it did the same thing.
It has been parked since then. Tonight I cracked open the master cylinder and the fluid reservoir for the rear brakes (the front one) was a little less than half full of fluid. I just flushed and filled the brake system a few months ago and I know there is no air in the lines. It definitely should not have been low at all. There are no external leaks either that I can find.
So I'm thinking I got a bad seal in the master cylinder, but I have a couple questions.
1. If fluid was leaking into the brake booster, could it be sucked into the intake and cause it to idle the way it was?
2. Anything else I should be looking at here?
I can't imagine any good reason for it to have idled like that all of the sudden. Almost all of the engine electronics are new and the IAC is clean as a whistle.
I think the ol' TC is getting her revenge for being forced to sit dormant for 10 years!
