Exclamation Stalling, stalling and more stalling !!!!!!!!

I'm like soooo over it !!

Random stalling at a sudden stop like a light@ first ! No sputtering or hesitation @ all.....just like a silent death !
Now I have to keep my foot on the gas while in Neutral and time my shifting
( major pain in the ass ) !!!!!!
It always starts right up if it dies.......but then, same @#^%& again @ the next stop !
Took it 2 several car repair places.......half the time they throw there arms in the air
and tell me they wouldn't even touch it !!??
The ones that do, call me and tell me that they have no fucking CLUE what could be wrong !!??
You fucking kidding right...wrong ! I get it all the time and I'm done with those fucking dimwits that call themselves mechanics ! You think I'm driving a lamborghini !!?
This is the stuff I had replaced lately...

5 Years ago:
ECU, Fuel pump, Alternator, Ignition switch / column.

Last Year:
Brand new Clutch and Transmission.

This Year so far :
Spark plugs, Battery, Starter, Fuel relay

I need some answers before I end up on the Headlines........I'm half way there

I'm so sick of the runaround that I want to VOMIT....and yes, MURDER !!!!!!!!!

I'm really pleasant and easy to get along with, but I can tolerate only so much before........ SO HELP ME GOD !!

Check the breather hoses running to the plenum as well

I think a clogged PCV filter(?) on the passenger side valve cover can cause this. But I'd start with a stepper motor and setting the base idle. Are there no rover specialists or dealers in your area?

Is the check engine light on? Doesn't the 94 have the little code display box? I'd think your symptoms would trigger a code. If not then that might help diagnose the problem too.

As others will confirm, lots of issues can cause stalling. The stalling you describe - driving fine, stalls at a stop, starts up fine - seemed to be cured in mine by cleaning carbon deposits in the stepper motor and in the various hoses leading to the intake.

Used a can of sea foam and cleaned everything out. The stepper motor and hose from the pcv leading into the throttle body. Worked very well and eliminated this type of stall. Google the terms to find images pointing their location, and search here or google to learn about cleaning with sea foam.

Had the same issue with my old '94, turned out to be the ignition module, which was solved by installing the ignition module relocation kit. The fact that the bad voltage regulator kept cooking the ignition modules didn't help. If I remember, the kit is STC1856.

Good luck!
Tony.

While you are trying to figure it out you can also run a can of BG44K through your gas tank to clean out the fuel injectors.

Probably a stepper motor. If it is stuck closed then the engine isn't getting bypass air under deceleration and it is conking out. If it's running it's likely not an ignition module. I would also check for vacuum leaks, like maybe a hose that looks good but really has a crack, or there's a hose not connected somewhere.
If, after you do all the vacuum checks and install a known-good stepper motor, it still stumbles, then look at the ignition module. All that does is transcode small EM pulses into timing signal.

Yep ... Get a Chevy Astros 1986 one from autozone for $40. Install takes 30 seconds. Reset ECU. Done.

Don't touch your base idle or let anyone else near it until everything is running as we'll as possible. That is a good way to really screw shit up.
