Question about 1999 Mercury Sable
My ABS light comes on and off intermittently and I am not sure what that means exactly. My father-in-law just replaced the front brakes (disc) and replaced both rear brake boots (I think that is what it is called). I just bought the car 4 days ago it has 112k miles on it and am also having trouble with hesitation, I have already replaced the spark plugs, spark plug wires, cleaned the throttle body, fuel system cleaning (Berrymans - i think thats the brand - B 12 Fuel system cleaner) and ran nothing but premium gas in it since I've had it. I also just replaced the front oxygen sensor and the only thing that seemed to make a small difference was the plugs, but the hesitation is still there, especially when it is below 40 degrees outside. Any suggestions?

ABS has nada to do with car hesitation. The blinking light may be indicating the presence of air in the lines or insufficient hydraulic pressure and/or improper bleeding. That has to be checked out
Hesitation could be caused by a fuel delivery issue, dirty injector, dirty fuel filter, bad fuel pump, computer settings or cold temp sensor for proper fuel mixture settings.

Hesitation problems can be caused by a number of thing's on vehicle's with electronic fuel injection , not like the old days of carburetors where most likely it had a bad accelerator pump . Throttle position sensors (TPS) can get a worn spot that would act just like a bad accelerator pump . MAF sensors (mass air flow ) Can also cause Hesitation plus ruff running , bad fuel economy , a IAT sensor ,(intake air temp ) ECT - engine coolant temp. sensor can also cause this problem . Unless you want to replace all these parts i suggest you have it diagnosed by a qualified repair shop that has the electronic diagnostic tool to test it .
ABS light on , DTC- diagnostic trouble code could be set in the EBCM - electronic brake control module . could be a wheel speed sensor getting ready to fail .

I was looking under the hood, and noticed that i could hear air rushing around. I found that a vacum hose had decayed and cracked. After i replaced that, everything has been fine

Well, this is just a guess, but it sounds like you may be running up against your rev limitter. I know what my rpm's are in both my 4cyl escort and my v8 porsche,@ 70mph its about 2800 ;-) I suspect you have a manuel trans? Shift a little sooner or get it chipped, in this case reprogramed.

Two are in each exhaust pipe near the connection to the header and two are at the outlet of each catalytic converter. Upstream and downstream.
