98 astro hard to start in the morning only

[MeMalato]

I have a 98 astro van. Hard to start only in the morning...keep it cranking it will finally start..run rough abit...turn the car off....restart it runs ok...check engine light finally came on one day...MIsfire #4 cylinder...plugs, wires ect..Ok....once the van is warm abit...it starts right up...no problem. Only if it sits along time..like in the morning. I think it may be a bad coolant temp sensor or #4 injector..any thoughts?

My neighbour has a 1995 Astro that was doing that, morning, and rainy days. Mechanic found a crack in the coil pack some place, replaced it they have not a problem since.
