i just ut a ported throttle body on that my friend gave m all i had to do was put my map sensor on and now it idles wierd from1 grand to1.5 gran....what do you think can be wrong my friend was saying it could be the tps and its a d16z6 motor.. thanks for any help

 

Now, me and the mad scientist got to rip apart the block... and replace the piston rings you fried

 

But seriously it could be IACV-faulty map sensor,improper porting job(too much), possibly TPS any CELs?
