Hello and welcome.

My name is ***** ***** I will be assisting you today.

What was the determination that the coil on cylinder #2 was bad? What did the spark plugs look like when you removed them? Were they discolored in any way?

They was discolored and it had the code that said multi miss fire and miss fire cylinder 2

Plus it has some whitish smoke coming out the tail pipe now

Ok, white smoke is an indication of water/coolant entering into the cylinder or oil burning from poor engine sealing. 2 things needs to be done at this point, remove #2 spark plug and look for water or coolant on the end of the plug, if there is water or coolant you have a head gasket issue. If no water is present look for oil on the plug and do a compression test on that cylinder.

It is my goal to give you 5 star service, so please give me a 5 star rating before leaving the site today.

No water on the end of the spark plug and it starts to idle okish after it runs for a min and no milk white ish in the oil but smells rich at the tail pipe

What does the end of the plug look like? Black, white, clear?

Black kinda gray but I did put new ones in and I noticed that when I take it down the road and stop it spits some fluid out the reservoir on top of the engine and seen a couple drops coming out the tail pipe with the white smoke but it hasn’t loss any power/speed but it smells like radiator fluid

It sounds like you have a head gasket problem, you can have a die test done to confirm.
