i just did a b18 swap in my 89 civic hatch and i cant seem to get it to run right, it idles just fine but it cuts out at half throttle and i was wondering if anyone had any advise?

 

Please be a little more specific. Does it die (engine shuts off)? Does it bog? Are you hitting a rev limit at a low RPM? Are you throwing any codes? You should be. What harness/ECU are you using?

 

yeah it bogs at about half throttle and yes its throwing a code 4 (crank angel sensor) and a code 7 (throttle angle). my computer is a stock 90 ls computer (obd0) and its a stock harness thats been pined, and no the car doesn't die.
