Question about 1998 Jeep Wrangler
1998 jeep wrangler 2.5L 4cyl check engine light is on codes 1682 1391 0320 engine has been misfiring alot
Code 1682 indicates low battery voltage. This could be a problematic alternator, which would likely cause misfiring. Autozone should be able to check this for you for free.
Code 1391 indicates the computer can not see the crank or cam sensor signal. This would likely be a result of the misfires.
Code 0320 indicates the crankshaft position sensor reference signal could not be found while the engine is cranking.
All of these issues point to either a cam/crank sensor malfunction or a charging system problem, either or both of which could cause the misfiring.
