My 96 TA failed PA emissions the other day. The shop didn't have time to diagnos the codes so I thought I would ask some real experts.
Codes are 0400 and 0420
400 is the EGR flow
420 is Catalyst system efficiency below threshold bank 1
The only test I was able to do myself so far was to push on the EGR valve, and the eng ran rough as it was supposed to.
Does the combination of these two codes point to a specific problem?
Thanks for any input.
