93 Legacy Touring Wagon "Turbo" UPDATE
Posted: Fri Oct 06, 2000 9:58 am
Well I have replaced the plugs and the Cam angle sensor. My wife thinks the plugs have made it run smoother and I thought maybe we had a solution.
However, yesterday it did it again. She thought she would test it and as she accelerated to 80mph it started to cut out again. She was able to revive it before stopping but it backfired several times.
I will check the ECU for codes later today and I should be able to pick up the plug wires this afternoon.
Next I plan to replace either the coil or Mass air. I know the Mass air is expensive so could I trade the coil with my 91 wagon?
Thanks again to all.

Hi guys,
just a short comment on the MAF sensor. I´ve had the same problem
with my car as well (1992 Legacy Turbo, EJ20 engine) after running it
on a performance intake filter (JR filter, abt the same as K/N) for 1
1/2 years. The symptoms where the same as described here, and I first
tried to change the air chamber bypass valve (which costed me abt
$100), but then the car left me on the road and I tried by loaning
another MAF from a friend, and voilá... The MAF costs abt $400
here
in Finland, so just as Josh said, you don´t wanna change it before
beeing sure that its broken...
Good Luck !
