New here. I have read alot of great feedback on different issues so I thought I would give my problem a shot. 02 forester started missing at idle, runs smooth at 2500 rpm. error code shows missfires on 3 and 4, swapped out plugs with bosch, problem gone for two weeks then started to run rough again. put in new wires and it runs ok but still lopes at idle and runs fine at about 2000rpm. Engine light on or flashing constantly.

also check resistance on coil showed 14 across 1,2 and 3,4.
