i have 1990 towncar [signzture series]. the car was running fine then it
started to stall every once in awhile [ when i came to a stop at a
light/stop sign] the car would immedately start up again. so i went and
had a oil change with flush [get out any sludge], had the injectors
cleaned [ with process used at delta sonic(thur vacuum line from brake
booster)] also changed the fuel filter. problem still presisted and has
gotten worse [ i constantly stall when coming to a stop and even slowing
to a stop] now the car won't start right away; i have to wait 5-10 minutes
[then it will start] i swapped out the distributer module , swapped out the
idle control valve and motor. the problem still persist. don't think
anything is wrong with wiring harness. play with it when car was running
no change. any help with this problem would be greatly appreicated. thanks

You didn't get your injectors cleaned thru the vacuum hose on the brake
booster, you got your engine de-carbonized. Injectors are cleaned by
removing them from the engine or by connecting a pressure canister or a
cleaning machine with a pump to your car's fuel system and running a
cleaning solution thru your car's injectors. Any competent repair facility
should provide this service. While you're there purchase an hour or two of
diagnostic time and it'll save you a bunch of money. Try this link if you
need a shop to help you work on your car. Best regards

If you are intent on persisting with the random shotgun parts-changing
approach, your next target should be the EGR valve and its modulator and
transducer. After that? Well, gee, how 'bout the vehicle speed sensor,
clean the throttle body, and...ummm...service the crankcase ventillation
system in its entirety, including the breather filter that's a damned
nuisance to get to, so it gets ignored until it's clogged up.

Or, y'know, you could get it in for proper diagnosis. It's equipped with
onboard diagnostics that will likely give at least a hint as to where the
problem lies.

Dan, that response should be standard for a lot of posts here!
