Glad the fix was simple - as is just about every repair on the Grand Marquis.

We just bought a left over 2006 GM with the handling package. I am accustomed to doing or at least understanding our vehicle maintenance. What is a source for the Factory Service Manual?
 
Thanks in Advance.

1998/99 Mercury GS Stiff Steering by amcardriver

Only 50k on the clock, regularly check the power steering oil and this weekend checked the pump, but from time to time the steering feel gets a bit stiff. Its soft in straight line but hardens as I turn the wheel left or right and then it eases off as the car runs into turn. The same when straightening up. Can't think what can be wrong saying that the oil and pump seem to be fine.
 
Tyres are less than 12 months old and wheels have been aligned and balanced. Very annoying feeling but main concern is safety when driving at speed. Any suggestions please?

Sounds like you need a new IAC valve about $50 from autozone and an easy install.

Engine light on by collins14

My Dad owns a 2001 Grand Marquis. He said the engine light came on this morning- the car has about 58K miles.
 
I have owned cars where the check engine light comes on at 60k just as a routine maintanence type thing. Is this true with the grand marquis also or does he need to be concerned and bring it in to the shop?
Thanks

Check for a low coolant level in the Reservor.

And make sure the gas cap is on correctly and tight, this can also trigger a CEL. If it's none of the above, it's probably a sensor.

What is sounds like is that you car misfires. If it is only happened on idle , I'd believe in the Idle Air Sensor, but otherwise, I'd start checking vacuum hoses and EGR valve. Drop in vacuum can cause change in fuel mixture and engine could stutter, as well as burn more fuel. If vacuum is OK, start going through "electrical" route - plugs/coils/wires. If that checks out check fuel pump + injectors.
