I replaced my spark plugs and ignition coils on a
2004 jeep grand Cherokee limited 4.7. Once I got
everything back together that jeep sounded like it
ran great but now there is a blowing noise coming
from the engine. Like there is air blowing out. What
could this be.
a vacuum leak..is a good guess...
Do you think I just didn't out the air filter or back on right. And will this cause any damage if I still drive it.
