Found the problem....I changed the Idle Air Control Valve. Thnaks to all that answered my question.
Two things I can think of:
Carbon build-up on the injectors; solution: speed on the highway (65+ MPH).
Idle is set too low; solution: find the idling screw and turn it up.
You probably have a 4.6 motor? If so you may have egr passageways plugging up. Although they usually are a problem whem warm if this is true. Next guess is a sensor such as a coolant temp sensor. It monitors the coolant temperature and tells the computer to adjust the fuel/air ratio. It feeds it more fuel when cold to warm it quicker. If the sensor is telling the computer bad info it may be starving or dumping too much fuel in. The computer controls the idle (no adjustment).
I had similar problem on a 96. I changed the air mass flow sensor and it ran like a champ. Took about 15 minutes. Very simple. Part costs about $85 remanufactured. Dealer tried to charge me about $300 to replace!!!
It's most likely the IAC (idle air control, or something like that). I had a Towncar with a 4.6 V8 engine with the same stalling situation. If yours is a 4.6, I can tell you that it's probably the hardest part to get to that I have ever worked with, but is do-able. Good luck!
Change the fuel filter first. It sounds like it's starving for fuel. If that doesn't work, have the fuel pressure tested for a bad pump or regulator.
if there is a clicking noise then you need a new starter.... if no noise then test the battery (local parts store will test for free)... if battery is bad then you need a new cylanoid
Need to know more about your car year make and model
try adjusting the idling level
FUEL PUMP??
Yes, a person can get a diagram of the PCV valve location in a 1989-1999 Mercury Grand Marquis. This diagram would be located in the maintenance books found in auto part stores.
Cranks and turn over are the same thing. It may crank or turn over and not start. If that is the case, find out if it needs fire or fuel and go from there.
On Mercury, you'd weigh 28.88 pounds.
The shift interlock mechanism probably needs to be repaired. The owners manual probably gives instructions for temporarily overriding this, but it would be best to have it repaired.
If its causing you the trouble its giving me my suggestion would be to roll it into the middle of the road scrap it or burn the bloody thing.
how to changing engine coolant on a 1993 mercury grand marquis gs.
what is the part called where the water pump is connected to on a 1996 mercury grand marquis -------------------------- That would be the engine
Might be you alternator. Happened on my 1997 grand marq a couple of weeks ago
I was looking at a ( 1998 ) Mercury Grand Marquis Owner Guide and it shows the body as being ( 78.2 inches wide ) I'm not sure how much the outside mirrors would add to that
On a 1999 Mercury Grand Marquis : The Original Equipment engine cooling thermostat would have been ( around 192 * Fahrenheit )
Physically, yes. It would be best to consult an interchange reference to know if the wiring and programming are compatible.
I would say ( No ) I was looking at the 2002 Mercury Grand Marquis Owner Guide and it doesn't show any reference to a cabin air filter
On a 1999 Mercury Grand Marquis , 4.6 liter V8 engine : The Original Equipment engine cooling thermostat would be : ( around 192 * Fahrenheit )
Likely the fuel filter is clogged so you need to change it. If you can keep the engine running by pumping throttle a few times at start up, and then it runs, check the filter; cost about $10.00. On My 1999 Mercury Grand Marquis I had to replace the Idle air control valve because it did stay running until it was warm
On a 1996 Mercury Grand Marquis , 4.6 liter V8 engine : Bank 1 is the passenger side of the engine Sensor 2 would be AFTER the exhaust has passed through the catalytic converter
The Grand Marquis is body-on-frame (same platform as the Lincoln Town Car, the classic American limo) and the 300 is unibody. Why would the 300 be sought after and not the Grand Marquis? They compete in the same price range.
The shocks are there for a reason. Removing them would cause damage.
