Hello and welcome to JA!!!
I'm Billy and i will help you with your question.
Since the stalling does not happen all the time, then you are right the fuel system is the first to check.
But i need you to check the
for clogged lines, and i need you to check the pressure regulator....
the best way to check this problem is by having a fuel pressure gauge attached to fuel rail while driving the vehicle.
And when the engine stalls you check for pressure changes. If the pressure is well during the stall, then it is something else than the fuel system (although i doubt it).
I suggest you do the following:
put injector and fuel system cleaner in tank.
clean fuel lines to and from tank using compressed air
the vehicle has 160,000 miles fyi
and revv the car a few times after cleaning your system.
Will the injector cleaner take some time to show any effects?
if you put the injector cleaner in an almost empty tank (has less than 4 5 gallons) and you drive the vehicle and revv it up a little bit, the cleaner should give results after about a 30 min ride
While you're checking, i suggest you take a look at the air cleaner and the spark plugs.
Air cleaner is clean. plugs will have to check.
the symptoms you describe don't point to a spark plug fault, but it doesn't hurt to check...
ok will try the cleaner. If problem persists, does the chiltons manual show where to hook up a pressure gage
it's on the end of the fuel rail
the fuel rail is attached to the injectors
any other suggestions? I will go and try the cleaner
no....i think after trying the cleaner, you only have to conduct the pressure test, which gives you a definitive answer on wether it's the fuel system or not.....(i still think that the fuel system is the culprit)
so if the cleaner doesn't do it and I do have a pressure problem what is the next likely prolbem
I take it that is replaceable (haven't looked) or adjsutable
difficult? ex[ensive, somehting a dyi'r could do in the garage successfully?
not expensive at all.....
a diy'er could change it easily......especially with a chilton service manual at hand.......
wouldn't take more than an hour

OK thanks again. If you any other tech thoughts prior to me signing off please let me know.
Summary: 1- cleaner, 2- fuel lines, 3- pressure check, if pressure check fails then change: pressure regulator, if pressure check fails again change fuel pump.
Hope you solve it from step 1......good luck
