1988 Ford Mustang LX 2.3L Poor Idle Quality, Misfire, Poor Fuel Economy
Posted to Ford Driveability on 10/28/2011 11 Replies

Problem Child, Came in Shuddering and Shutting off, Did a Tune Up and problem got better but still shuddering, replaced Ecu due to lock up issues on the trans. I have a random misfire, soot on the plugs and a shudder when engaged in gear and a rough idle.
