the sad thing is ford is not covering the intakes on their grand marquis as i have recently found out.i had to pay the dealer to fix an obvious design flaw in the part.the replacement part has even been improved.the section which fails is now made from aluminum and there is an added support bracket behind the alternator.
#1941 of 3300 92 GM Fog Horn under the hood
Jul 06, 2003 (8:14 am)
I own a 92 GM with 186,000 miles. After we had the transmission rebuilt at 75,000 the car has been wonderful. About 6 months ago the shop said the vibration sound I was hearing was the fuel pump going up. I took it back recently - the noise is now very loud and sounds like a fog horn under the hood. The mechanic said he took the air filter off and put his hand over the hole and the noise stopped. He did not know how to fix it. The noise is worse. The car accelerates when the noise starts; I have to put the brakes on to slow the car down when that happens. If I'm driving along the road and have my foot off the accelerator, when the noise is there the car will surge forward and drift, surge forward and drift, as the noise intensifies and diminishes. The same rhythm as if I had the AC on and the condenser? was working... I would like the car to last another year. (Looked at Lexus the other day and found the discussion on Edmunds about transmissions - in fact there seems to be something wrong with a lot of cars we were looking at - VW Passat, Lexus ES300, Acura TL, Subaru Outback...) GM did not get a good writeup in Consumer Reports - is Ford making them as good as they used to? Forgive the long email please - I don't know whether to keep the old or buy somehting new...

Thank you!! I will call the mechanic tomorrow and fixing it will give us the time we need to decide on which new car to buy.

Hi all -- I just bought my first CV -- A 1992 LX with leather and the whole bit. Bought it at an estate sale. Just before the previous (and original) owner died, he had the AOD tranny rebuilt at a national tranny chain. It accelerates fine but I find it decelerates slowly (especially at mid to higher speeds). When I take my foot off the gas, it takes a bit too long for the car to decelerate without having to use the brakes. Tranny shop said that the rebuild has to "break in" but I don't really buy that. Any comments? Is this just a factor of the mechanical nature of the AOD vs. AODE? I'm comparing the tranny to a new Japanese tranny, so maybe I'm just not used to a mech AOD. Otherwise, the CV has got to be the best used buy going!

"When I take my foot off the gas, it takes a bit too long for the car to decelerate without having to use the brakes."
If you want more "engine braking" take it out of 'Overdrive'. When in O/D and you take your foot off the gas, it's really in "COAST" until you get down to 37 mph, then the transmission shifts down to 3rd.

Wow, thanks for that. I didn't realize that OD wasn't supposed to shift until it gets way down to 37mph (which makes a lot of sense now). Any problems if I shift to D at higher speeds? Or it it better just to brake? I suppose brake repairs are cheaper than transmission repairs.

Does to '03 model has the TSB about gas tank safety? If it does, can you just bring your car in and have the dealer fix it for free - I assume this is a very easy fix since Arizona police can have their cruiser fixed in a few minutes.
