Hello, I have a question on my 99 escort. Today I replaced the air filter, the car was running fine and the engine was quite as a sewing machine up untill this point. After I replaced it drove up town and the car was spark knocking so badly I was concerned it would damage the engine and it started immediately after changing the air filter. When I got back home took the new filter out and put the old dirty one back in and the engine was instanley smooth and quite again. Also with the new filter it was idling much higher and very hard to crank. I hate running it with the old filter but would rather do that than listen to the engine sounding like it was coming apart. What would cause this? Also I replaced the old filter with the same exact filter, a fram from wally world. Anyone else ever experienced this?
