'96 not a whole lot...but I don't really know. My 83 grand marquis freaks
out when there are vaccume leaks...the last time my power brake booster
croaked, it would idle really strange......mostly at really high speeds but
still.

O2 sensor?
We have a 96 Mystique and has trouble starting then staying running.
If I run cleaner through the throttle body it runs great for a day or
2 then back to usual. At times the engine runs up to 1500 then back to
800. I have replaced the upper sensor previously and cured the problem
again breifly. Could there be a problem with the throttle position
sensor?
Thanks for the help in advance.

You might also want to check your air bypass valve. They are notorious for
getting gunked up and sticking which could be why the strange idling it's
doing. When my Mustang does what you're talking about I remove the valve
and clean it thoroughly with carb cleaner then reinstall it.
