hesitation / stall upon acceleration / deceleration 200

Happy Thanksgiving, everyone,

Having an issue with my '93 244 . If I could pick your brain...

Here's what's happening:

If I'm inching up to a stop sign (or into a parking space, etc.) and push
the accelerator just slightly, and then release quickly, RPMs drop and the
engine wants to cut out, and sometimes does stall completely. But it starts
right up afterwards without issue. And runs like a top.

I have replaced the crank position sensor, but this did not really help.

Any ideas?

Thanks very much as always.

Sounds like it is related to the throttle position or things connected to that area.

Pull the accordion hose behind the AMM that goes to the throttle. Look for fine cracks in the voluteor places there might be a hole rubbed into the side. I use a bright light stuck up through the middle.

While you have the hose off clean the bore where the throttle plate flips. Use come carburetor cleaner on a rag. Don't soak the bore as this can harm the throttle position switch.

After all is clean check the throttle position switch for proper clicking just as the plate shows any sign of movement. Adjust on the switch if needed by rotating it under its two screws.

Look around for any other vacuum lines for cracks or looseness. Look on the under side of each end of every hose as this is where cracks or splits hide out.

Post back if you need more hints but from what you say, it's related to the pedal action that makes the problem repeat itself.

That's My best guess, aside from, how much turkey I get to eat?

Phil
