Bit of a strange one. Bought the car about 8 weeks ago. Engine light was on from day 1. The car drove fine, no misfires/hesitations and perfect idle. I figured a faulty/bad sensor, possibly 02 and put it on the "to do list".
About 2 weeks ago I changed the thermostat. The temp guage now reads just under 90, I have hot air from the vents, and fuel comsumption is way better. Another job off the list.
Nearly a week to the day from putting the new stat in, the engine light suddenly went out. As I said, it had been there from day 1 of my ownership, and at this stage nearly 1500 miles of driving. It's been a week now and it's stayed off. Happy days
But I want to know why. The thermostat couldnt have been the problem could it ?
I havent done anything else major that could have effected it, apart from driven the car !
Or is this just another quirk of owning an Alfa ?
