so....let's say the mechanic can't figure out the problem..... should I have him replace CRANKshaft position sensor, as a start? he said they might replace the CAMshaft sensor, and go from there. but I allready dumped $450 into this car in about a week, and 2 mech visits. =/
i'd hate to see this problem make me get rid of the car.

With me sitting here at a key board, it’s easy for me to say go for it and replace the sensor. But with everything I’ve read here and if I haven’t missed it, the crank sensor is one of the things you haven’t replaced.
I’ve replaced a lot of them just for this every same elusive can’t put my finger on the problem and it’s cured the issue.
After saying that, it’s still a crap shoot that it’ll fix the problem. Now if the shop that has been trying to find this has any feelings toward you and their pride they’ll admit that this is a chance and do the labour at a break even valve. With the proper tools it’ll only take them, oh about 15 minutes to do and if you’re willing to go the parts everyone may win?

PS: Have you printed this thread off and given it to the techs that are dealing with this; if so what was their reaction? Did they show actual interest or just fluff it off?
If they have closed their minds on your input, then it’s time to find someone who will keep an open mind. Not that they are not good at diagnosis; it’s just a new perspective on an issue might turn a corner for everyone?

well, I cant print from this computer since I have no printer, but I did give them a list of possiblities that I heard from you guys here.
Just recently started going to a new mechanic, and they seem like allright guys.
I'm not sure if they will do the work for basically free, just to narrow down the problems. They should be calling today, hopefully, with some good news. This is just an on-going nightmare for me.

We keep several new and used parts in stock for these type of issues . Ask them to check all your ground circuits as well . That dang Crank Sensor does not like to leave a trouble code trail that is for sure 0-o

well its been at the shop for 2 days now, and they havent called back. I guess I should just call them and tell them to replace crank position sensor if possible.

UPDATE:
just got the car back AGAIN from the shop. They drove it around for 2 days and it wouldnt stall for them, BUT - they did change a broken crank sensor, so I'm hoping all is well finally. I'll keep you guys updated.

kick me in the nuts and call me charlie....
got back from the shop last night, fine. about a half hour later I tried to go about 5 miles away and it stalled about 5 or 6 times.
It seems as if the problem occurs after I drive it once, shut it off, then try to drive again.
I can't take this anymore....in and out of the shops countless times, $500 + just last week......

Does that vehicle have a passlock security system ? Is the ignition switch a combo type with the electric circuits in it ? Is there any play at the key when you try to turn the car over ?

i have no idea what passlock is. no play with key in ignition.
no clue what type of ignition, either.... =/
i thought maybe it was just something to do with temperature or moisture, as it seems to not stall as much when it is colder out.
but it stalls when its dry or raining. I dont get it. GOing back to the shop today.

so...could anyone give me ideas of what this could possibly be narrowed down to?
sensors changed: Mass Airflow, VSS, and CPS.
no symptoms of clogged cat. converter, yet the problem pretty much went away when exhuast was broken before the cat., though it DID stall twice in the broken state.
I tried to clear the computer by disconnecting the negative battery terminal for about 20 mins, went to start it and it wouldnt start at all. Half hour later, started right up. Didnt stall on the 20 min drive home, then the next day I drove about 5 mins and it stalled.
It seems to act up after I drive it, park it, then drive it again..... but it's totally random and gives no warnings whatsoever.
Pedal could be to the floor or I could be on the brakes, stalls either or.
I just wish I could end this nightmare of a problem and have a reliable vehicle again.
could this be a fuel pump or filter problem? coil/ignition module? Can't they test these parts at the shop?!
I figred that it would run like crap or wouldnt run at all if the pump was bad....

Well I don't want to be the joy-kill here but after reading the replies on your posts, I feel compelled to share with you my sister's story - in a nutshell.
She had a 92 Park Avenue (same engine as yours? I don't know) She had so many problems that sound just like yours it wasn't funny. The scariest part was the car dieing out on the expressway with her kids onboard.
After repeated visits to numerous mechanics and close to two thousand dollars in "let's try this", "this has to be it", "I'm sure this will fix it", she finally had enough and got rid of the car.
Bottom line, no one could properly diagnose a the problem and it was never fixed. Has sanity is back after she bought a new car.
Everyone has their limits...

yeah I do believe the Park Avenues are basically the same exact car.
Ive heard so many stories about problems with these Buicks, and Im kicking myself in the ass for buying this one....but it was only $700 and seemed very sound when I got it. I really hope these guys can fix my problem, as I'd hate to try to sell it for next to nothing after I dumped $600 into it in just the past 2 visits alone.

yeah this problem is a nightmare. still no word from the shop. I'm basically giving up hope, and am going to prepare for the worst. Every other time I've gotten it back, it runs fine for 5 mins, then 30 mins later I stall not even 1/4 mile down the road from home. Its VERY VERY aggravating and I really dont want to sell the car for next to nothing because of this.
pretty much, what it narrows down to, is coils/igntion module, or the computer itself.
someone mentioned it could be something in my gas tank, which is clogging the pump....but I dont know.
I also heard that the fuel pumps go bad in these cars, since they are inside the tank? and ....the gas is what actually keeps the pump cool. but...Im not sure if the pump is in the tank or under the hood....

According to a quick search on the web;
"The filter is located under the passenger side directly under the door area. The car will have to be jacked up to access it. Be sure to follow the pressure relief procedure before disconnecting the filter."
Hope that helps...

Hey I got mine fix today or for now it seems
we changed the mass air flow sensor and it is now running like a champ
i couldn't remember if this is something you had looked into or not
If you do look into it realy shop around I found the same exact part at 3 different shops the prices ranged form $105 to $195 and even more if I went to the dealer.
Good luck hope maybe this will help you as well
Jon

just read back thru the prev post and saw you did change maf sensor but was just thinking that maybe your air filter might be in bad shape. If so it could let a lot of debris by that could easily clog the maf sensor. You might try taking out the sensor and cleaning it. They sell a product called mass airflow sensor cleaner for about $6 a can.
the sensor is real easy to change to, there are only 3 screws holding it in.
Good luck

yep. MAF, VSS, and CPS all changed. Last I talked to the mechanics, they basically took the words out of my mouth when I was like "the other place I called said the only problems they've ever had with these Buicks is Crank sensors, coils/ignition mod., or connection problem..."
I'd think the mechanics would check things like air filter and fuel pump right off the bat, no?
and wooley, when I had my MAF sensor changed, the car ran fine for about a full day. then...BAM, stalled. I hope your problem is fixed, because this REALLY sucks. They've had my car for 3 weeks now.

This thread has to be a site record in length! I'm lost. Bryan - how about starting a new one with where everything stands right now and all that has been done and ruled out? If that MAF sensor worked for a whole day perhaps the new one is a problem??
One oddity that fools folks from the beginning of time is plastic in the fuel tank. Particularly a non soluble peice that would usually be vandalism. It was a trick once that I heard of to fool all. A wrapper could float around and would be sucked over the pick up screen and when everything quit it would just take its time floating back away and randomly just do that again. You could test everything but almost never figure it out unless you took the gauge/pump and screen out or if it wasn't there right then you were still screwed - dang near need to replace a tank over something stupid like that! Hope that couldn't be it - could it?
Just a thought and I do suggest starting a new thread with an outline of events along the way. Perhaps this can be saved,

sorry...i've just been stuck here at home a lot now, and fuming about this damn car.
i've had someone tell me that my problem might be exactly what you said - something floating in the tank and clogging. but...I cant see it being an act of vandalism, for I have a lock on my gas cap. Unless it is something else floating around in there.
and as for the MAF sensor...the one they removed was bad. It was put in by the mech we stopped going to, and apparently he put a used one in. the one in it now is brand new.

 I thought by now you'd be posting a pic like the one above as the final solution to this problem!
At some point you start to question stuff you've already ruled out which really stinks. Sometimes things like this just need a whole new person to check out the problem and don't give them a history as at this point it probably screws up the diagnosis.
If it helps there have been some funny problems with gasoline lately with the plastic gas tanks - not this car and the junk they tell us is gasoline is just barely gasoline now and that's a problem!
Wish you luck,
T
