It's the SOHC engine, the spark plugs that were changed two weeks ago all look like number 23 on the chart you sent me.
The misfiring occurs when you accelerate from a dead stop, specially if you do a quick start, it doesn't do it if you go easy on the gas pedal, but it will do it as soon as you press on the gas pedal to increase your speed.
I believe the plugs from cilinder 3 and 4 were misfiring.
Also when reving up the engine the car begins to misfire above 3800 RPM.
I will follow your advise and try the autolite iridium spark plugs, can you suggest the proper autolite iridium plug for this model car?
