Was it doing the same thing before you replaced the parts? If not, recheck your work.


Yes but it seem to get worse the more new parts I put on the ignition is ripper apart on the steering colom where you put key at don't know if there's a ground missing


Let me ask. When you say, "when the choke goes off" do you mean when the coke retracts after warm up and the engine returns to normal idle, the engine miss fires? If so, try disconnecting the choke and see if it has any effect. The timing may also off, which would cause a miss fire.
