Check engine light? Did you put the plug wires back in the right order? Is your timing set?

 

Sounds like an injector prob to me imo. Are you throwing any codes?

 

SAME thing happened to my friends lx with a gsr. We tryed so many dizzys and different coils/rotors. We took it back to the shop and the guy fixed it within like 5 minutes..told us we had the firing order wrong I doubt that was what was wrong, he probably messed something up during the swap..but you never know. Double check it all.
