1987 New Yorker - engine quits at random

Hello all. Hate to make my first post a plea for help, but here goes.

I have an '87 New Yorker with the 2.2L Turbo engine. In the last few
days she's started stalling on me, and I want to try and narrow the
problem down before having to take it to a shop.

Five times in as many days, the car will up and die on me; no unusual
noises or vibrations, just shuts off. It's happened twice pulling out
of parking spaces, twice stopped at a light/sign, and once while I was
coasting under cruise control on the freeway. The only common factor is
that each time, there was little or no pressure on the gas. I've had it
happen anywhere from thirty seconds after starting the engine (parking
lots) to fifteen minutes (freeway).

If I try to start it again too soon after it dies, the engine cranks
but doesn't catch - given a couple of minutes however, it starts right
back up. When she's running, all seems normal; even after restarting
from a stall. Nothing cuts out after the stall, and all my gauges seem
nominal; save for the battery gauge which drops a couple notches.
Getting the engine controller error codes returns nothing useful, just
a 55 - end of file code.

The only maintainence I've had recently was an oil change, and a dose
of fuel-injector cleaner in my last fillup. I've done some research
thus far and have a couple ideas, but nothing concrete. Any thoughts?

 

Sounds like the pickup to me. check to see if it is cracked. they usually go
and sisplay those symptoms. Take off the Distributor cap and rotor. It plugs
in and is placed below the rotor.

 

The first thing to do is have the throttle body cleaned out, this may be
causing your problem since it only happens when the gas pedal is not
applied. The other thing could be a slow to respond AIS motor not being
able to maintain the proper idle position.

Thats what this site is for. making plea's for help

Take a good look at the vacuum lines, on a car that old they are likley to
be split/rotted, plastic connectors broken

 

I can only think hall sensor like others have said, otherwise possibly a bad
fuel pump but the high vacuum must somehow be connected. I would say EGR
sticking but since it is accompanied by a delayed restart I think you can
rule that out. Check the fuel pressure just for shits and giggles and maybe
leave a mechanical gauge hooked up while you drive around. Weird problem,
hopefully you can find the source.
