i started my car early this morn. cuz there was frost on the windows... anyways.. starts up fine.. little timing chain rattle..*not too worried about it because my other contour does it too* but anyways... i'm backing out of my driveway and all of a sudden it starts to howl.. and the RPM's start surging really bad.. could it be my egr is clogged or what? i wanna know before i dump money into mods...
