84 crown vic stalls

[tommysevens]

usually at 25m.p.h.sometimes at 55m.p.h.after it shuts down i have to wait about 3 minutes and start it again.then repeat the whole procedure 2 more times.then...down the highway i go with no problem.i think it's clogged fuel injector any help would be greatly appreciated(it may save my life)

[tommysevens]

i think i'll clean the egr valve....and of course the injectors prolly need attention...that other thing i did wright down on the back of my state income tax envelope that h.r.block sent me....all in all my problems are solved!!! this is one of the best sites ever...thanx "t7's"

[tommysevens]

it almost passed...
and it stalled when it was waiting in the line.
i took the egr valve off...and it was stuck...
had to hit it with a brass hammer!
i'll have to look at the idle air control,also the MAP sensor?
(whatever that is)

If you cleaned it and it is still sticking, replace it!

it seemed to unstick..the seating and valve were corroded together...the car was sitting for a couple of years

[cobradude360]

id replace it and if that doesnt work which it probly would but if it doesnt id try a throttle positioning sensor

[tommysevens]

because the vehicle has fuel injection....i'll have a look at the inertia switch located on the hinge of the trunk....there's a reset button on it.
in case of an accident the fuel pump shuts off automatically

[tommysevens]

if i charge it up on sunday.i can make it to work every day.
i'm getting a solar battery charger...that'll get me to a terminal and i'll hook up the charger.that's life on the road:shrug:

[tommysevens]

i'm going to clean the maf sensor with contact cleaner(thanx to bigger john and the rest of u guys for the info)next i'll get an ignition control module and if that doesn't work...a pcm relay.
...feel free to add any advice!

[tommysevens]

i changed the ignition control module....that seemed to help a little.
today i stalled 1 time.now it's almost time to see if my fuel pump is still working.and i want to check the timing...and i can't find the timing light

[tommysevens]

i'm not getting any spark when the engine "shuts off"
my next question...what's a "pcm relay"

[tommysevens]

replaced alternator and belt.fixed pipes going from the catalytic converters going to the pollution control hoses...now it purrs like a kitten...still has the stalling problem

[tommysevens]

my 84 crown vic...is now at hwy.50 auto repair
maybe they can figure it out

[tommysevens]

they couldn't find the problem
they say there is a short somewhere

I had a VERY similar problems over a 2-year period and had all sorts of stuff replaced without correcting the problem.

FINALLY I tracked down a wiring problem that was probably shortcircuiting the ECM. Look at the wiring leading to the series of solenoid switches mounted on top of the driver's side valve cover to see if any one of them is close to the intake arm of the air cleaner housing.

In my case the intake arm was "drooping" downward because the rivets fastening it to the main body of the air cleaner housing had loosened because of metal fatigue. This permitted the air clean intake arm to come within a fraction of an inch of the wiring thereby creating a short circuit. There does not need to be much exposed wire to create a problem. In my case the exposed wire was where it bends over the plastic clip securing the wires to the solenoid valve.

I repair it using "liquid tape" available at any auto parts store.

My CV has never stalled since.

Good luck
