Had one on my 99 Tahoe. It started to run rough took it to a shop and they said the first thing they look for is a oil type filter when the customer complains of rough running engine. He said the oil from the filter fouled the engine sensor. And yes it was a new filter not overly oiled. Went to a dry cone type AMZ/OIL air filter and have not had a problem since.
I do run a AFE big oil type filter on my 98 12V Cummins. It has no sensors to foul. AFE owners came from K&N and their filters are supposed to be much higher quality than K&N.
