A miss under load is usually an ignition miss. Take off the wire at the coil and start the car up, if you have spark the coil is fine. Next remove the wire from the plug, get the boot close to the engine and start it up. If you see spark the wire is fine. That would then leave the spark plugs. Is it possible he put junk plugs on the car?

I agree with Flatrater. But I wonder what brand wire and sparks plugs the mobile mechanic put in. From my experience its best to stay with the OEM GM Packard wires and AC Delco Rapidfire platinum plugs, IMO.
