I own an 87 syncro in Indiana and decided to gut the catalyctic converter
since the vehicle already has over 100,000 miles on it and I figured the
catalyctic was contaminated and not doing much good anyway. The exhaust pipe
is now showing more carbon instead of burning clean. Will leaning the mixture
screw cure this? I thought the ecu did this automatically through readings
from the co exhaust sensor. Any advice other than 'buy a new catalyctic'
would be appreciated.
