Purchased a 2003 ranger with 2.3 was running rough took it and had it checked and showed error code p020 cylinder 2 injector Circuit Malfunction.

toke it to a mechanic who said it was the ignition control box that was causing the problem paid 300.00 to have it changed it run fine for a week the started same thing all over again.

had it checked again came back same code.
