I had code 1-2-1, Air Mass Meter, as well as code 1-2-3, coolant temp
sensor.

The sensor was changed and the air mass meter was changed. That was 4
months ago.

Last month, the code 1-2-1 came back and soon after the Check Engine
light came on, the car almost died on a few occasions. I unplugged
the battery to reset the code and everything was fine for two weeks.
Then I got the code 1-2-3 again. I unplugged the battery to reset
code and eveything was fine for 3 weeks. This morning I got code
1-2-1 again and the car almost died on 2-3 occasions.

My garage tells me it could be the computer.

Anyone can help?

Thanks, Sam.
 
Hello, I have had something similar... Check the pins on the computer plug.
I had a couple of them bended and these caused a lot of similar problems to
my car. You never know...

It could be the computer. Or perhaps it's the airbox thermostat stuck
in the full heat mode. This would direct rather hot air over the air
mass meter constantly. This is indeed enough to fry an AMM in short
order.
