engine overheated, now hesitates

[naja]

Please help,
Two weeks ago, my 94 SHO overheated. I stopped right away and called AAA.
I replaced the radiator, the waterpump and the thermostat. When I picked it up from the mechanic, there was oil in the plug wells and some spark plugs were almost out. They pushed them back in and the engine run again like new. Now the cooling system seems to work fine but yesterday, on a highway (65-68mph) the car hesitated (like a miss?)for few seconds when I pushed on the gas. Today it did the same thing to me, three times. It seems like things are getting worse because the same thing just happened this evening on a stop light.
What went wrong? Something serious?
Thanks a lot for any help.

Maybe fouled plugs and/or wires. Might want to address the oil leak thing.
Any computer codes by chance?

Yes, the CEL comes on and goes off. I'll go check the codes at autozone this afternoon.
Thanks

I'll bet it is either a TPS sensor bad or Oxygen sensors. Also, you may want to clean your MAF sensor with some electrical contact cleaner.
