got the zc motor swap running kinda good but i think something may be alittle off. if first gear at like 4000 rpm it will back fire also if your just rev it up it ill back fire. in second, thrid gear if you floor it, the motor bogges down real bad, i changed pulges and wires, also shoot it with a timing gun, it showed it was right on the red mark on the crank pulley, could it be a vacume leak. any help would be great.

 

How about the cam timing? It could be off a tooth

 

possibly, i turned to motor over manuily and piston came to tdc, and cams were right on the marks. ill check when i get off work.

 

any CELs? check your map sensor!

 

code 4 and 14 i think thats it
