ok here goes, i have an ls b18b in my 91 hatch, the car will bog up until 2,000 rpm's if i just small on the gas. i want to know if i'm runing the right manifold cause it seems like alot of stuff is missing maybe i'm runing a newer year manifold. How can i know for sure, thanx in advance

 

by the way the head is of a 93 teggy and its a jdm b18b maybe who ever did the swap didnt do a good job of wirign the car and also the car is a dx

 

Check your timing.

 

that could be part of the problem but that wouldnt explain why i'm getting a code 43 on my ecu
