Stumble w/Throttle

[Kenneth]

Thanks for the replies.  I unplugged the MFTS and while the behavior seemed 
better somehow, some stumbling was still there.  It needs replacing, again, 
anyway.

I'll try a different MAF sensor next and see if that does anything.

Sounds similar to symptom my '91 200q had all this summer. It finally threw 
a code indicating a problem with the MAF sensor. I checked all sensor 
connections and finally removed the sensor and saw a broken wire. I replaced 
with a used MAF sensor and problem solved.

The temp gauge issue is possibly our old nemisis, the MFTS. That would also 
affect engine running, but not a stumble problem, AFAIK.

Disconnect the multifunction sensor hanging below the coolant manifold. May 
be a bad sensor.
