Ok so the car has been misfiring for some time and pulled the codes off and it says injector circuit 2 open. So I replaced the injector. Started the car it ran fine for couple of miles and started misfiring again with same code. So I thought ok maybe fuel injector wiring hareness is bad so I replaced that it ran fine for 10 seconds then misfired with original code injector circuit 2 open no other codes just that injector. I'm at a loss on where to go from here. I've read from some other post that the next problem would be the ecu/ecm but the symptoms they were saying would be a tell sign for a bad ecm aren't present with my ecm so I have no suspicion that the ecm would be the problem but I could be wrong. If you have any advice it would be appreciated.
