went offroading last weekend, hit a few bumpy spots on the tracks, and parked the car almost a mile ahead.
turned car off, wouldnt turn back on and no power at all. popped the hood to find a disconnected battery terminal and the air filter cone disconnected from the hose.
put eveything in place and it turns on normal, but i may have driven a mile with no air filter through some heavy sands.
now i can almost swear i can hear weird sounds from my engine, but it may be my paranoia.
whats the worst that couldave happened? and is there anything i can do to make sure no sand filled in? flushing? .... ?
