Thought I'd share what I've learned recently about the fuel delivery system in this car: Had the check engine light, with poor idling, poor acceleration (bogging when I hit accelerator), and occasional stalling at idle, which is a huge safety issue given the vacuum assist brakes and power steering.

Brought to my mechanic who found the p0172 (rich on fuel mixture). He diagnosed a failed O2 sensor, which was replaced, to no effect. After that, he recommended a new throttle body assembly thinking that the idle motor or throttle position sensor was pooched. These can't be fixed--gotta replace the whole TBA. I went to dealership, bought and installed the part, reset EFI, all to no effect. Finally, on a whim, I pulled the mass air flow sensor out (small philips screwdriver needed), cleaned it with a thimbleful of rubbing alcohol, a q-tip and shot of compressed air. Re-installed and reset compter (pulled EFI fuse B). Voila! problem solved! No bogging, better mileage, no stalling. Could have saved about $700 if I had tried that earlier. Consequently, I've got a perfectly good throttle body assembly sitting on my work bench. Anyone with similar experience?

I'm having a similiar problem, and have now removed, cleaned, and replaced the MAF. Where do I find EFI fuse B so I can reset the computer and clear the code (the check engine light is still on)?

Thanks for your help.
