- The new air filter was crammed into the box like an accordion. The rubber gasket was torn off of the filter on one corner. A real hack job!
I'm guessing that with the air filter compromised, the computer could not correctly read the incoming air flow and temperature and then compensated for it with a rich mixture.
The van seems to run and smell much better now.

WIth the air filter comprimised like you say it might be a good idea to clean the MAF Sensor, use a real soft paint brush and maf sensor cleaner. The sensor may have a dirt film on it from the improperly placed filter. IS the filter box seem to be wider in the middle then the ends? If so you can drill a hole in housing and install a piece of readu rod or bolt and pull it back into shape.
Glad to hear it is running better.
