The evap coil can be changed. However, depending on what kind of A/C unit you are talking about, it might make more sense to replace the whole unit. Also, before you invest in the time it takes to do the work of replacing the coil, make sure the rest of the unit is in good condition.
You need to replace the Distributor cap and rotor. Be sure that the coil wire is not WHITE or RUSTED on the ends were they go in the cap and coil, If they are then replace the COIL and the plug wires too. Just be sure that you use Factory Parts not after market.

No you have to replace it.
for the cost of a coil you should replace the whole unit... An a coil costs me about 280 dollars and takes about 2 hours to correctly install and pull a vacume on...I can buy the whole airhandler...with heat pup and electric heat 10kw for 350 and can install it in about 2 and a half hours done correctly with a vacume and using duct mastic ...not foil tape....have a great day and good luck...Donald Unless it is a furnace, then there is no airhandler and the only option is a new coil.
I have a 97 cavalier with a 95 engine and i had to replace the whole ignition module and the coil packs are 1/4 and 2/3 that's how they are numbered on the coil packs so 2 coil packs but make sure you know which one isn't firing to replace them and u will have to replace you spark plugs after that.

You need to replace the Distributor cap with a factory GM cap. be sure to check the coil wire where it goes into the coil, pull it out and it should be shiney on the end. If not replace coil and wire too. That will fix it.
You should have C.O.P. ( coil on plug) there are no wires.
