RANDOM MISFIRE

2004 Chrysler PT Cruiser • V8 • 71,000 miles

2004 PT Cruiser Turbo-71,000 miles.
Engine light blinks and car runs rough when the light blinks while idling. Checked by mechanic- code for random misfire 4th cylinder. The light stays on driving, but runs smooth if light is not blinking. When Have replaced plugs and wires and tightened gasket. Mechanic thinks that the next step is to replace the fuel injector to the 4th cylinder. What do you suggest?

If you have spark, pulse, and correct compression readings on #4, and you have ruled out vaccumm leaks at #4 cylinder intake runner, Then yes fuel injector #4 would be suspect.
