Okay gents, who knows about those fault codes? My Check Engine light came on yesterday evening on the drive home, with no apparent symptoms other than a fairly high idle, 1500-1800rpm. After checking the essentials, oil, coolant, I warily made my way home to check the fault codes.

Socket 2 turned up code 2-3-2 first, then 1-2-1 when triggered again. These were the only two codes it gave. Socket 6 gave me the heart-warming 1-1-1.

If I check the FAQ, I'm told:

1-2-1* Faulty signal to/from Air Mass Meter Wiring fault to or in AMM Various driving problems; fuel consumption

2-3-2* Fuel trim (lambda control) too lean or too rich at idle }If too rich: high fuel press., leaking injector } various driving problems

That's all very nice, but where the heck do I start? The other "various driving problems" that showed up during the trip to work today were 1) a throttle that would seem to cut power from time to time, like a clogged fuel line, and 2) a 'touchiness' to the gas pedal, causing sharp (almost high-performance-like) acceleration, rather than the smooth, steady surge of power I'm accustomed to. Oh yeah, and the gas mileage - If I squint really hard at the gas gauge, it seems I can almost see the needle moving downward.

I'll look around the brickboard archives to find the location of the ever-susceptible AMM, and check that this evening. But is there anything else to look for?

Thanks in advance for any input.
