#31 of 39 Crown Victoria Gauges by chrismiller2 Jan 21, 2007 (4:24 pm)
I have a 1999 Ford Crown Victoria and was wondering if the gauge cluster of a newer model crown victoria such as the 2006 with the tachometer would work in the 1999.   Thanks for helping, if you can.

Replying to: joe110 (Apr 04, 2006 1:21 pm) Hi Joe: I own a 04 CV Sport that came with dual exhaust. Each bank on your engine has a cat before it goes into a single pipe. I owned an 04 Cv with a single exhaust & had duals put on it.No problems at all & you will see a marked increase in performance with the duals.
#33 of 39 intake manifold 1998 by greeley Feb 10, 2007 (11:12 am)
My manifold is also cracked. Looking for recall info for it but cant find it. Also when i went to the dealer they said that it was past the 7 year warranty period and even if there was a recall they don't fix it. I think that is bull(*&^. Any other advice or stories about intake manifolds?

#37 of 39 Throttle body blues by gearhead11 Feb 27, 2009 (7:42 am)
I have an 84 crown vic 5.0 throttle boddied carb. I just can't seem to get it to idle right. it either idles high or too low and when it idles low it surges. Iv'e replaced dist cap,plugs,upgraded wires and hotter coil. I've checked for bad vacuum lines. Any ideas? Is there any way to bypass the eec-iv computer and run a regular carb?
#38 of 39 MAP to MAF conversion '90 CV by dj7trypp May 19, 2009 (10:41 pm)
Anyone know how to switch the computer from a manifold air-pressure sensor to a mass air-flow? Do I have to replace the entire induction system? If so, what are some good aftermarket choices?   Also, the engine likes to cut out when I go around corners... I can''t even find anybody that's had the same problem.
#39 of 39 98 Grand Marquis by ts128 Jun 22, 2009 (4:22 pm)
My Grand Marquis has been doing some strange things lately, it all started late one night when my daughter went out to get something out of the back seat, when she opened the left rear door the car began to turn over like it wanted to start, then it stopped, the next time it did this was when we were driving it, it started grinding like crazy, so the first thing we thought was to replace the starter, didn't help, next was it went to FOMO where they said it was a loose wire under the dash, it didn't happen again for two weeks and then it started doing it even worse, so I inspected the steering column for wires rubbing or loose, found nothing, checked the ignition switch and all looks to be good so I moved on to the starter relay and changed it. I'm hoping this fixes it but just wanted to see if anyone else with one of these cars has experience this. Thanks, Tim
