Replying to: crownvic2 (Apr 29, 2006 7:55 pm) take some electrical contact cleaner and spray the mass airflow sensor. This will clean it, and might solve the driveability situation.
#54 of 87 transmission/engine noise by pepperdog Nov 22, 2007 (7:58 pm)
I have a 2003 Crown Vic Police Interceptor with 35000 miles on it. It was a light duty car for the Sheriff and his deputy, and never used for patrol. My problem is that it seems the engine and transmission roar louder than they should on acceleration. I have a 1995 CV and it is quiet and does not roar on acceleration. I know the 1995 car has lot's of insulation whereas the cop car has a vinyl mat and very little sound damping. Everything works correctly and the car runs great..no issues with tranny or motor..except they seem a little loud. Also, the gas pedal is hard to push..it seems to have a lot of resistance, and gets very tiring on long drives without cruise control. It doesn't seem like it is binding, just hard to push. Can the accelerator cable be adjusted?
#55 of 87 Crown Vic transmission slipping? by pacobun Dec 02, 2007 (8:22 am)
i have a 2007 Crown Vic with 33K on it. I am having a problem whereby anytime the roads are wet, the powertrain seems to act out. It will usually happen when snow or ice are on the ground, but this makes no sense to me. First, the car will feel like a skip hits it. Then eventually, a lit wrench appears on the dashboard. The engine lihgt also illuminates and remains on. The cruise control also goes out. If i restart the car, everything is back to normal until the skip happens again.   I had this on my 2006 crown vic, and the dealership didn't know what the problem was because I could never get it there with the wrench lit. Anybody know what i'm talking about or have experiences with it?
#56 of 87 output speed sensor insufficient input by sparky28 Dec 02, 2007 (1:50 pm)
2001 Grand Marquies 4.?L engine 32 K miles. The service engine light came on and the overdrive on/off light began to blink. Took it to autozone for a scan and it came up with the output speed sensor insufficient input code P0720. Is this possible it's just a bad sensor or can this be an input problem to the sensor? I can cycle the O/D button on the shifter a few times and the light will stop blinking on and off. Does anyone know where the sensor is located? Is this something I can change while changing the transmission fluid?

Replying to: captain131 (Sep 14, 2007 2:34 pm) Hey just wanted to say that i have a 1991 crown vic and the tranny went out and i believe what your probably expering is either the od band is out or there may be a throttle valve which is a cable that goes from the top of the motor to the tranny and the top piece is mad out of teflon and it has gotton hot and burnt up. if those are not the case check the rear end my went out with the same shuddering and when it went out i was going down the insterstate and the axle and all flew out so be carefull. anyway i have work on tranny for the ford people for 19 years and there just saying they dont know couse they don't want to work or they want to wait for the right time so they can rip you off. just chek those couse after i fixed mine rear end and tranny i have never had trouble. i have owned 3 crown vics and all have had tranny trouble. good luck
#58 of 87 transmission troubles by deangelotl May 17, 2008 (6:30 am)
Ok I have a 94 grand marquis and the trans just started acting up on me yesterday. It wouldn't shift into park and the gears fear loose when I shift to them. I found a bolt in the driverside floor board and it have no idea what it goes to. Please give me some kind of feedback on this problem.

Replying to: deangelotl (May 17, 2008 6:30 am) 1. Not shifting into Park may require a minor linkage adjustment.   2. Not knowing how many miles since you had a fluid change, perhaps that is due. Remember to also drain the torque converter and install a new filter in the transmission.   3. The bolt found on the floor board may be related to the need for linkage adjustment, but I doubt it. Your Mercury dealer parts manager would know by showing it to him.
#60 of 87 94 grand marquis trans by deangelotl May 18, 2008 (2:27 am)

#61 of 87 drives like a derailed train... by sts_endeavour Jul 15, 2008 (3:34 pm)
Hey guys,   My 2005 Mercury Gr Marquis LS with 111150 miles sometimes feels like the wheels are going to fall off at any moment. I'm pretty sure I have a warped brake rotor, but would that cause the car to shudder like nervous Nelly while the brakes aren't engaged? Otherwise I have had the alignment inspected (multiple shops say it's fine) and the only items that aren't stock are the tyres, the Michelins have been replaced with Goodyear TripleTreads. I keep the car well serviced - engine and transmission fluids and filters changed, as well as the rear differential fluid... All in accordance with the owners manual. I'm kinda lost here because I'm starting to set off seismometers. Replies to this message: dannyodoul (Jul 15, 2008 4:47 pm) euphonium (Jul 15, 2008 8:18 pm)
