electronic air cleaner spray

problems flow sensor air mass?
my truck starts, but remain more than usual 2 seconds. air masses may be defective or dirty i sensor cause this problem? Recently i oiled my K & N air filter a few days ago and I realized how much oil sprinkled over it, already was dripping from the air filter housing. I tried cleaning the sensor with a break cleaner, but still doing the same thing. any suggestions? Do I need a new sensor? planning IM trying to clean with a little electronic cleaner as soon as I get to the store, idk maybe that will do the trick ……. please help
attempt to disengage the sensor from the start and see if it works better if it's not the mass of air and pull the filter after the air mass trying to see if the filter is running if you do then again clean the filter and oil again.
