Stiff throttle & surging cruise control & other new 700 owner questions 700 1990

You'll want to look into this oil leak quickly. From what I remember it might be a dangerous one - affecting your timing belt.

Anyhow, My 740ti has a very stiff throttle pedal. I think it's so that the spring is strong enough to close the throttle, and that it needs more force due to the fact that it's cutting off boosted intake air.
You can lubricate the throttle cable though, I believe there are instructions in the FAQ. I've never tried it with mine.

My cruise control is VERY aggressive. If I'm going 40 and it was set to 75, it will kickdown (sometimes into second) to get up to 70. Mine also does get on it to maintain speed (like on a hill) or against wind. It could be an indication of poor mixture or an intake leak, but it could be normal.

I'm not sure if the blower motor can be wired backwards. I know there is a resistor pack for it, but it may or may not have diodes in the resistor pack.

The vent servos could be the issue, but I suggest that it might be a vacuum reserve tank or one-way valve that's not working right. The turbo cars seem to have issues with this.
Is your blown air coming out of the defroster perhaps? If you hold a hand up to the vents, does the flow drop when you move from vacuum to boost?

And yes, the rear defroster uses very fine wire through the glass.

Good luck and post back,
Will
