2004 Crown Vic odd problem

Anyhow, the 2004 Crown Vic is acting funny these days. It has less than 26,000 miles on it. I had it out to Oregon and back in October and it was just fine the whole way. Matter of fact, out in Nebraska there was one stretch where there was a whole line of drivers messing with one another. During a lull in the nonsense, I seized the opportunity and passed all of them. When I glanced down at the speedometer it was at 107.  In the last few weeks, occasionally while stopped in traffic and at idle it will act as if there is a momentary interruption in the fuel flow. It will run rough and shake for a second and then it will immediately recover on its own and act perfectly normal again. This is so far very sporadic and unpredictable and can go quite a while between occurrences of these spasms. A new fuel filter has made no difference.

Any ideas? I'm really scratching my head over this one. Thanks.

Thanks for the ideas. I think I'll do the fuel pump next. Sometimes, those

basic possibilities just escape you for a moment until you get someone

else's input. 

I'm thinking about just selling it off and getting an older car and pocketing

the difference. The power locks are starting to be troublesome, the windows

will probably be next, and I'm just getting super weary of these newer

vehicles and all of the hassles with gadgets and electronics and crap. All

of the extended warranties are gone now, so it may be time to just get

rid of it before anything else goes wrong and the expenses just start mounting

up.

Tires are 4 new Michelin Symmetry. This is a Standard, not an LX and not a stripped 'S'. Seats are cloth, not leather. All power gadgets including driver's seat. Keyless entry and CD. Full wheel covers. Looks like an unmarked and is often mistaken for one. I have been behind people at times and they have actually pulled off to the side of the road. Guilty consciences, I guess. 

The interesting thing is that it's one of the last to come from the factory without the anti-lock brake system.

It may be 224hp and single exhaust, but it will definitely get out there and move. Even at the above-mentioned 107mph jaunt, there was still power left.

I found a 78 XR7 cougar I'm seriously thinking of buying with a shelled 351W.

 

With Carl coming up with his 72, he's bringing me a engine and some parts, 351w, so I may end up buying that car, get it running, and use it for a driver and have some fun.

 

Cheap, junk yard project .

 

As much as I'd love a CV...I want an CVPI, frame is reinforced...and the bigger brakes, etc.

 

 

Will load ALL the 351W stuff I have and bring it with me Sunday.

Tranny (FMX) coming with it!
