The advice I've gotten from two independent shops here, one being the guy I've gone to for more than five years, is just what the dealer said: Until they can reproduce the problem, they can't be *sure* replacing the controller would fix it.

300B: If it's the MAF, wouldn't there be other driveability problems, poor gas mileage, etc.? My mileage is tip-top.

In the meantime, I'm having the shifter bushing(s) replaced to solve a nasty rattling I've been hearing in the cabin on ripple-bump roads. Seems to me I saw a post here that suggested that, just possibly, if the shifter isn't making the right contacts, the transmission could get confused and not know what gear to go into. Maybe that'll help, or even solve, the issue?

Daveuz, I don't know the board rules about posting the names of shops outside the Good Shops section. Have a look there; I've posted the contact info for my regular mechanic. Or you can PM me.
