My 93 850 glt w/96k started stalling the last coupled of days before its
warmed up, weird its 85 degrees in upstate NY. it usallly happens
between shifts, its also takes a while to get it restarted.

at one point I got desprate and remove the hose to the air filter box
to the throttle body to open it up to fresh air, that work but tripped a
code,

it also seems low on power and rough idle.

to date I have done the following maint; (in the last year)
plugs,
wires,
cap & rotor,
fuel filter
air filter
clean flame trap,
clean throttle body
can if fuel injector cleaner
oxygen sensor


97 850 sport wagon 70k (sold it do to mounting problems)

hi there i will tell ur problem i changed most of the things u have changed and gues what its the fuel pump relay u have 2 change its located under the fuse box just remove the fuse box cover under bonnet and u will c 1 big relay usually says 103 on top of relay change it its cheap and ur problems are gone ;-)

thanks ronjon for the photo, that what I thought it was,
i ordered it last night, I also unplugged and replugged
my maf sensor 20 times and fill it the tank with super
so far no stalling,

thanks,

p.s. I bought this car new, had just about ever problem

anytime.

'bought it used at 90k. Now at 123k. Besides main seal, no major problem.

I had stallings due to bad gas, (dirty fuel injector, now I use 93 octane from a good station) and due to sticky fuel pump relay or main system relay (two different relays).

The relay related stalling was during driving suddenly engine, break and steering power will go off (since, all tied to the accessories belt!).

'not sure about your problem.

I posted one about rough idle recently, you may try that:

Wires & distributor cap related rough idle: A coworker of mine told me that when you replace ignition wire set and the distributor cap/rotor, you should do it at the same time. His reason was that if these wires start leaking, it will generate higher voltage then there should be. As a result the rotor and the cap can go bad with in seconds (after installing with bad wires) and sometimes you cannot see any burn marks on the cap/rotor contacts. I am not sure how accurate this is.

ronjon any chance you have a digital photo of the part????

Which part, the non-return valve?

Ronjon

what ever part solved your rough idle, it a $18 check valve I think,

I must correct that 40% of the rough idle has been solved with this.

Ronjon

Hold on, I am at work. Let me get the camera and take pic for the system and pump relays.

I am not sure should I send it to your e-mail or load it here. Let me know.

Ronjon

NICE!!!

us 93 850 owners have to stick together

My Indy told me to ONLY use Chevron and/or Texaco gas (aren't they the same company now?). At any rate, I already do so . . .

I only use super unleaded,

anyone replace there maf sensor or try to clean it

I think this may be my problem

It is not only what type of gas you get but also how old the station is you are getting it from. Some say that medium aged stations are good, not too new and not too old (Goldilocks breakfast job??).

I tried one full tank over the other and found out which one does not cause stalling.

I have problem with one BP but not with the other. Also, if they just fill their reservoir then all the sediments will be diluted, not a good time to get gas there.

Ronjon

That can be upwards of $2.10 per gallon here in San Francisco. I must settle for regular unleaded with the occasional infusion of super unleaded.
