Finally ended up chasing all the wires and found the pins for the crank position sensor were pushed out of the big connector at the brake booster. hope this might help someone

FED UP by knilgnissim

I have a white 94 Grand Marquis, the car ran perfect until it started with a light tremble between 35-45 mph.I changed the oil, oil filter, gas filter put new spark plugs nothing helped then i put new spark plug cables, and everything was alot better, but still a light tremble, it goes away when I step on the gas, but its coming back, it almost seems like its burning the cables too quickly, or I dont know maybe something with the transmission, I honestly dont recall when was the last time they changed the trans oil, i know its not as often as it is for the motor oil. dont know, but would like to;cause im FED UP with these mechanics that charged my mom $500 for changing I dont know what the heck. If anybody has any idea or tips Id really appreciate it. thanks

I have a 2008 Mercury Grand Marquis. This is the first car I can remember owning where the steering wheel does not lock into position after parking. My understanding is that it used to have this feature, but it was eliminated. Anyone know why?

sounds like your experiencing the classic transmission 'shutter'. Change your tranny fluid with mercon v and that should fix your problem. It did for me, used to surge between 30-40. Here is how to do it

I Second the suggestion to change the tranny fluid, filter, & remember to drain the torque converter. Mercon V is the most expensive, but it lasts longer.

1998 Grand Marquis Rough Idle by jcro

My wife and I recently inherited this car from her parents. It ran great until a couple weeks ago when it had a rough idle. It only lasted for one trip in town and ran fine the next day. A couple days ago it began to idle rough again. The check engine light came on and it soon had a strong sulfur type smell. I'm not at all familiar with this car and I'm wondering if there is something fairly obvious I should be looking for. Any ideas? Thanks for any information.

Have the light scanned, it'll tell you what's wrong, and it can most likely be easily fixed.
