ok so I had a local shop swap a 1998 LS b18b1 motor into my 1992 integra LS, everything runs really well except I idle reeeeally strange, sometimes drops as low as 200 rpms, sometimes chills at 1500..a quick tap of the throttle usully drops it down some, but I noticed on my intake mani theres nothing plugged into the spot for the map sensor..what do I need to buy to get that hooked up..can an obd2 map run on my 92 LS ecu?? ..any help would be appreciated

 

Something is telling me no... I'd swap to the correct ECU
