I'll look into that; thanks. I cleaned the MAFS again, with similar results--car worked great for a few days. Started stuttering again. Based on this happening twice, I'm leaning toward thinking the MAFS is just on its last leg. Ordered a new one today (only $85). It'll get here in 2 days, and I'll test my theory.
I suppose with a 13 year old car, it wouldn't hurt to find all electrical connections I can get to and clean them up a bit.
