#54 of 102 knocking noises on my 94 crown vic... by hottmomma315 Feb 24, 2007 (9:23 pm)
My 94 Crown Vic just started making knocking noises and a ping type of noise every few seconds and when accerlated it shakes and acts like it isn't getting enough power. All fluids have been checked. What do u think could be the problem? Replies to this message: euphonium (Feb 25, 2007 6:06 pm) jsylvester (Mar 03, 2007 8:40 am)

Replying to: hottmomma315 (Feb 24, 2007 9:23 pm) Would be helpful to know how many miles are on the CV. If in excess of 110k, don't overlook the coil on plugs, plug wiring, and mass air sensor.

Replying to: hottmomma315 (Feb 24, 2007 9:23 pm) Could be a lot of things, especially at it's age. But I would start with the ignition/timing system first.
#57 of 102 5000 or 3000 by fordenvy Mar 07, 2007 (8:32 pm)
I get my oil changed every 5000 miles, unlike the recommended 3000. My uncle worked for ford before buyout and told me that it was a waist of my money to change the oil every 3000 miles. He said it simply didn't get dirty enough to cause enough friction to do damage, so ford knows we only have to change it every 5000 but i think they have a scheme to get the dealerships more money for changing oil more often. what do you think?

Replying to: fordenvy (Mar 07, 2007 8:32 pm) It may go without saying, but hopefully you also change filters when you change oil. Otherwise, it's like putting a new diaper on a dirty bottom. Replies to this message: fordenvy (Mar 20, 2007 8:34 pm)
#59 of 102 Oil Changes by jsylvester Mar 08, 2007 (4:35 pm)
Your uncle is right - modern oil is far superior to what it was when you had to change it every 3,000 miles. Not to mention, cars run cleaner, so less contaminants get into the oil.   That being said, cars run hotter now than before. Therefore, on an engine understressed like the Grand Marquis, I'd go with 5,000 miles. On my wife's little Corolla, we still do it every 3,000 miles.   Oh yeah - I used 5w30 in summer, - 5w20 is too thin.

Replying to: serge99pi (Feb 09, 2007 8:25 am) I'd replace the fuel filter (about $9) and if that does not work have a shop check the fuel system.

Replying to: fordenvy (Mar 07, 2007 8:32 pm) I've always done around 3000. That's how I was taught growing up. Maybe I'm wasting money but the flip side is I've had a lot of cars live past the 200,000 mile mark.

Replying to: euphonium (Mar 08, 2007 10:01 am) I definately change my filters. Which comes to another point Transmission fluid, I won't change it for the entire life of the vehicle, why because I never have in the past and the transmission lasted everytime to about 120,000 miles, so why start? You're going to say to make it last longer, but I don't need it to last any longer than that because I'll be in new wheels by that time.

I just heard today that 5000 miles isn't going to be recommended by Ford on their new models anymore. Now it's going to be every 7500 miles.
