Hello. My name is ***** ***** you have the idle adjusted at initially?
Customer: replied 2 years ago.
like 3 turns and the further in i go the better it runs, but that dam kick happens , looks like they do when lower gear, is bad, same type deal
Expert:  Tan replied 2 years ago.
The initial setting is 1.5 turns out from lightly seated. What is happening is the engine is running lean from to much air and not enough fuel. Now a bad coil will cause the same symptom but you have replaced the copils correct? I suspect you have a bad gasket on the intake. Spray wd40 around the intake gaskets # ***** and 20. If the engine runs better then you have a bad gasket. Try this and let me know what happens.
