Digital meters have a tendency to smooth things out I always try to keep an old simpson on hand because analog cannot be replaced sometimes

I couldn't notice a definitive dead spot on the digital meter, but I DID notice that I could consistently get the engine to start doing the stumble parked under no load if I veeeery carefully held the accelerator at just the right spot. Coincidentally, the same spot I usually cruise at. I'm thinking you've nailed it, Deerhurst, and my TPS has a worn out spot. I'll report back once I've had a chance to install the new one.

No dead spot, but the wide open throttle position sensor wasn't working so I went ahead and replaced the TPS anyway. Haven't had a chance to test it under cruise yet but it does seem that the throttle response is a bit smoother. Will report back after some highway cruising today.

Started out fine but stumble returned on the highway. It is still much more muted than before, but I’m back to square one.

On a hunch I removed and thoroughly cleaned the Mass Airflow Sensor. The stumble is just barely noticeable now. Still hunting down the final cause, but it's looking like whatever it is was being worsened by a bunch of other stuff I've been tweaking.
