Hello. Did you have a cylinder 1 misfire before all that work was done?

Have you done a compression test?

Ok. All the other cylinders had good compression?

Ok. Can you get cylinder one on the compression stroke, and add compressed air using either a leak down tester, or a compression tester with a regulator attached? Listen for air coming out of either the exhaust pipe, throttle body, cooling system or crank case (remove the oil cap and radiator cap) The compression is going somewhere. We need to figure out where it's going and that's how to best go about it.
