Question about 2003 Mercury Grand Marquis

1 Answer

My 2003 mercury grand marquis has what I describe as lifter chatter for about the first three seconds after starting. Should I move up in oil weight? or take to shop?

Only does this when first starting in morning. Warm days and more so cold days if sits like eight hours or so.

The VA is buying me a new power wheelchair. The chair alone is about 375 pounds. They are going to install a Reese hitch and a carrier. I purchaced a Rear Power Chair Load Leveling & Air Suspension...


the system your describing is fine for your vehicle, just remember that the car will turn and drive a little different from the standard weight schedule and factory specs,, however , it will be just like having 2 Big adults in the vehicle all the time, so you should have no worries, the ****** weight your seeming to be worried about is within the limits, here is that described
If the ****** of the trailer does not exert enough downward force on the tow vehicle's hitch ball -- meaning that the trailer's ****** weight is too light -- a dangerous condition called trailer sway could result. If the ****** weight is too heavy, the steering of the tow vehicle will be affected.

2005 mercury grand marquis sounds like collapsed lifter or lifters passenger side front also knocking from sounds to be cat convertor


collapsed lifters are definately a possibility, what usually happens is the oil filter gets sucked in and restrics oil flow to the top end... change you filter, make sure the fluid it full, and see if that makes your vehicle sound any better.

I have a 2002 grand marquis with 65000 mi when the car sits ove night when i start it in the mornig it make a tapping sound for the first 4 seconds what could it be?


Most likely you are experiencing oil bleed down in the Valve lifters and Valve train. Using the incorrect weight of oil can also cause this problem and so can dirty oil and varnish in the lubrication holes.

What you can try are 2 things, both at a Ford or Mercury Dealer. They have "Lube Express" service where they can can install a Ford filter and oil. When you go, tell them you want a Desludge treatment before the oil change. It only takes a few minutes more.

You may have to repeat the Desludge treatment 1 more time before you can eliminate sludge as a problem. See if there is a difference the first time.

Engine is turning over but not sending fire to the spark plugs


take off the oil filler cap and look in while someone turns over the motor. If you don't see the lifters moving you probably broke the timing chain.
