Hopefully those will allow you to see whats going on

 

Is your firing order right? Double, triple check. Almost sounds like timing is way off, maybe you switched up your wires somewhere.

 

^ x2. Sounds like timing is off or spark plug wires out of proper order.

 

i didnt put the wires on car but i will double check it, if its not that then could the timing between the crank and cam be off by a tooth or two and cause this same symptoms? Again the timing we assumed the shop had done correctly

 

Could be... I did work on Jaromgi's 280zxt this last summer. Ever since he bought it, it didn't run right. Turns out the cam gear was one tooth off, and the distributor / oil pump shaft also a tooth off. Ran like crap, and got REALLY hot during light driving (glowing turbocharger and 3/4 to maxed out temp gauge). Fixed both problems, runs like a champ and stays cool.

You never mentioned this... and if a shop had worked on it and not fixed it, that's even more reason to CHECK EVERYTHING.
