KA24DE Stumbles on light throttle under load

[darkstarr]

So the problem is, when I first start the car it still starts and die's (Only sometimes) and every now and then when I am driving under light throttle the car will missfire is what it feel's like, but in neutral it will rev freely and under heavy throttle the car seem's to operate normally, the random missfire under light throttle is intermittant, sometimes it will happen other times the car will operate normally any ideas?

Change your spark plugs and also, check the wiring on them. My wiring was really loose and not hooked up right which caused these problems that you are experiencing. I hope this helped.
