Before the car died it had a nasty miss when under acceleration. Now that it runs again IT STILL MISSES (not that expected it to heal itself while it sat for a year and a half.)

I have tried several types of sparkplugs.... no help
I have put on new plug wires.... no help
I replaced the connector to the #1 injector.... no help
I replaced the air filter.... runs better!
I cleaned everything on the top of the engine with degreaser

The miss started after the top radiator hose broke and sprayed coolant everywhere under the hood. A mechanic said that this was probebly coincidental, but I don't think so.

Could the coilpack be intermittant?
Could this be the fuel filter?
IT ALSO SEEMS TO HESITATE UNDER ACCELERATION A BIT.

There is an occasional miss fire where I can hear a tiny backfire under the hood (in the intake.. not the exhaust.)

ANY IDEAS?

Are one of the 'several types of sparkplugs' Motorcraft fine wire plugs ? Your problem sounds familiar, I did the same thing. Go buy the fine wire, low resistance plugs, the Motorcraft plugs. Nothing else will work, and they will misfire on gentle acceleration, but not at wide open/high rpm acceleration ? I think you might be surprised by the difference in new, correct plugs.
