I got problems !

Scenario - Driving home and temp guage is goin crazy, From the N to the L and back and forth. Had to drive another 30 miles on it. Radiator had bad leak and was replaced. Wrong radiator put in and temp guage still moves up and down a little bit but not as bad. I have to go back to school and leave car at home. While gone correct radiator is put in and a leaking tranny seal is also replaced. Sister drives a few times and mom drives a few more. I come home 2 weeks after leaving it hoping to have it back. I pull it out of the garage and the engine acts like it wants to fall apart, VERY rough. I hit the gas and it feels like I have maybe 3 of my cylinders and whole car shakes. I take it straight to the mechanic and the first thing noticed is one of the plug wires is green. They replace that but the miss is still there. Hook it up to a scanner = no codes, all wires and plugs are sparking correctly, no vacuum leaks. They test everything they can in a short time because it is closing time.

Does anyone have any ideas ?????????

Sounds like it might have been bad enough to blow a head gasket or warp the heads. Obviously you'll have them check it out when they reopen on Monday. I have a feeling you may need a cylinder head job; you should also inspect each cylinder for damage.

Only things I can think of off hand is a clogged fuel filter, bad fuel pressure regulator or fuel injection problems. Start with checking the fuel pressure at the rail. This will either rule out fuel as a problem or not.

Like Alec said, you might have blown a head gasket or warped the heads. Aluminum heads are very touchy to overheating. I'd run a compression test on the motor and a leakdown test on the cooling system. If you have one of the two problems above, this will find it.
