i have a 91 escort with two problems....first, it wont run unless i unplug the plug on top of the air filter box. is this sensor the dead one, or something else?
and can it pass a test with it unplugged? smells pretty rich, but runs smooth.
second, it has a serious problem that i am callling blowby, but may be something else. there is a lot of smoke and oil coming out the top hose from the valve cover to the air filter box. if i dont contain the oil coming thru the hose, it fills the box with oil, and saturates the air filter...i ran the hose to a containment bottle, but it now smokes under the hood...is there a test or fix, or is this just a toasted engine? runs great and has no problem going over mountain passes, getting great gas mileage too....if only i could route the smoke into the air filter, and separate the oil...bottom line, i need to get this to pass an emissions test so i can change the title, and perhaps sell it later. any help would be greatly appreciated....
