A couple of weeks ago I went to take my car out one night, and the car was idling really badly - jumping between about 500 and 1000 revs. The car was showing just 10 miles of fuel left, so I thought it could be that, so I went out in a different car. The next day all was fine.
The problem happened again earlier this week - strangely again when low fuel, then fine since.
Today, with a brimmed tank, the problem came back - it feels ok when at speed, but at low revs and slow speed it's incredibly jerky and again idling really roughly. The engine management light also came on a few times (mostly flashing, but once solid for a bit).
My initial thoughts were either MAF sensor or coil packs. I've had MAF sensor failure on a couple of cars before, and it wasn't intermittent like this, which made be think maybe coil packs?
I can't get around to taking it to the garage until this time next week for plugging in, and just after any ideas in the meantime?
