Right guys need a little help. A couple of months ago I decided to follow to tutorial on here and drill my airbox. Did it and reset the ECU and it worked fine for a couple of weeks with a great sound. Then the famous air meter problem occured (1.0 12v) for the second time in just under 2 years! Anyway replaced the air meter again and reset ECU. Has been fine for a while until recently i started to notice the car was juddering around 3000rpm in all gears except 1st. Wasnt too bad apart from it being a little annoying and then yesterday on the motorway coming home from work the engine management light came on and stayed on and now when the car starts it is idling around 1600rpm instead of the usual 800 and vibrates very violently when the ignition is switched off. Just wondering if any of you know what this could be as like I said the AFM has been replaced already. I thought maybe the idle control meter might be faulty but what do you guys think?
